    OBJECTIVES: To investigate crystallography, translucency, phase content, microstructure and flexural strength of two commercial strength-gradient multilayered dental zirconia grades. METHODS: Two zirconia grades, i.e., KATANA Zirconia YML (Kuraray Noritake; referred to as "YML"; composed of four layers: enamel, body 1-3) and IPS e.max ZirCAD Prime (Ivoclar Vivadent; referred to as "Prime"; composed of three layers: enamel, transition, body) were investigated. Fully sintered square-shaped zirconia specimens from each layer were prepared. Microstructure, chemical composition, translucency parameter and zirconia-phase composition of each layer were characterized. Four-point and biaxial flexural strength of each layer was measured using fully sintered bar- and square-shaped specimens. Square-shaped samples were used to measure strength across the layers. RESULTS: For both multilayer zirconia grades, the 'enamel' layer contains a higher amount of c-ZrO2, which resulted in higher translucency but lower flexural strength than the 'body' layers. The characteristic 4-point flexural strength of the YML 'body 2' (923 MPa) and 'body 3' (911 MPa) layers, and of the Prime 'body' (989 MPa) layer were comparable and higher than for the YML 'enamel' (634 MPa), Prime 'transition' (693 MPa) and 'enamel' (535 MPa) layers. The biaxial strength of specimens sectioned across the layers was in-between that of the 'enamel' and 'body' layers for both YML and Prime, implying the interfaces did not form a weak link. SIGNIFICANCE: The difference in yttria content affects the phase composition and mechanical properties of each layer of the multi-layer zirconia. The strength-gradient approach allowed to integrate monoliths with irreconcilable properties.

    Structural analyses of niobium oxide (NbOx) amorphous film prepared with a sputtering method have been performed by using synchrotron X-ray radiation at SPring-8. The composition was determined as Nb2O5·0.8H2O from the measurements of Rutherford back scattering, X-ray fluorescence, X-ray absorption near edge structure, and thermal desorption spectroscopy. Structural information was obtained by extended X-ray absorption fine structure and high energy X-ray diffraction measurements. It was supposed from the experimental data that NbOx consisted of distorted NbOn polyhedra connected by corner- and edge-sharing. Structural models were constructed with reverse Monte Carlo (RMC) simulations. In the RMC models, the structural characteristics were successfully reproduced, and H atoms were, however, randomly distributed. Then, bond valence sum (BVS) constraint was introduced to the RMC simulation. As the results, narrower distribution in BVS was achieved for all the constituent atoms, and distinct OH bonds were effectively generated in the RMC model.

    Electronic structure of amorphous niobium oxide prepared by a sputtering method was investigated based on optical absorption and photoelectron spectroscopies. In the valence band photoelectron spectra, broad peaks without any characteristic components were observed. Then, theoretical calculations based on a density functional theory were performed to interpret the experimental spectra by using three Nb2O5 polymorphs. Among the polymorphs, M-phase with tetragonal structure showed better reproducibility than the other B- and R-phases with monoclinic structure. It was finally concluded that the amorphous niobium oxide had a similar electronic structure to M-Nb2O5, and it was supposed that the broad feature in the photoelectron spectra was due to the broad distribution of Nb–O bonds in NbO6 polyhedra, which was characteristic in M-Nb2O5.

    In this study, we examined the temperature dependence of the second-harmonic (SH) intensity and Raman shift in the langasite-type Ba_3Ga_2Ge_4O_<14> (BGG) and Na_2CaGe_6O_<14> (NCG) crystalline phases. The SH intensity curves revealed an anomalous temperature behavior around 370℃ and 270℃ in the BGG and NCG phases, respectively. Furthermore, as a result from the Raman spectral measurement, it was suggested that the anomaly observed in the lagasite-type phases originated in the A-site.

    Crystallization of the langasite-type La3Ga5GeO14–Ba3Ga2Ge4O14 mixed crystals in the stoichiometric corresponding glasses was studied by differential thermal and X-ray diffraction analyses, and by Raman spectroscopy. Although the glasses used in this study were multicomponent systems (BaO–La2O3–Ga2O3–GeO2), the langasite-type phases were singly crystallized in the corresponding glasses. The Raman spectroscopic study revealed the structural similarity on the scale of short-range order between the langasite-type phase and the corresponding glasses. This also strongly suggested the coexistence of Ga and Ge with six-coordination in the gallogermanate glasses.

    Nanocrystallized glasses with the composition of 40BaO・20TiO_2・40SiO_2, stoichiometric to fresnoite (Ba_2TiSi_2O_8), have been prepared by heat-treatment at various temperatures, and their optical properties, second-harmonic generation (SHG) and photoluminescence (PL), have been examined. The glass subjected to the heat-treatment at 760℃ for 1h showed a dense formation of Ba_2TiSi_2O_8 crystals with the dimension of 200-300nm, and maintained a visual transparency. Visible green light corresponding to SHG at 532nm was confirmed in the transparent Ba_2TiSi_2O_8 nanocrystallized glasses. The maximum second-harmonic intensity in the nanocrystallized samples was on the order of 1/100 when compared to that of an α-quartz single crystal. Furthermore, the bluish white PL with a peak at the wavelength of about 470nm was also visually observed in samples heat-treated at 750-800℃.

    Second-order optical nonlinearities for the langasite-type phases obtained by crystallization of corresponding glasses are clarified for the first time. It is confirmed that most of langasite-type crystalline phases can be formed by crystallization in the corresponding glasses without introducting of any impurity phases, e.g., the glasses with the stoichiometric composition of Ba_3Ga_2Ge_4O_<14>, BaGa_4La_2Ge_2O_<14>, Pb_3Ga_2Ge_4O_<14>, etc. We find that Pb_3Ga_2Ge_4O_<14> and Pb_3AlGaGe_4O_<14> phases exhibited strong second-harmonic intensities of approximately 100 times as large as α-quartz by means of a powder technique, demonstrating that those langasite-type crystals are excellent nonlinear optical materials. It is also suggested that the octahedral site is one of keys for second-order optical nonlinearity in langasite-type crystals.

    Crystallization behaviors of the glass with a composition of 25Li_2O・25B_2O_3・50GeO_2 corresponding to lithium borogermanate LiBGeO_4 have been examined. It has been confirmed that the LiBGeO_4 crystalline phase is formed at the surface of heat-treated glasses. The second harmonic(SH)generation is found from transparent surface crystallized glasses, demonstrating for the first time that the LiBGeO_4 phase shows optical nonlinearity. The SH intensity of LiBGeO_4 crystallites(powdered state)prepared through crystallization is about ten times as large as that of pulverized α-quartz. The SH intensity of transparent crystallized glasses(bulk state)with crystalline layers of 3-4.5 μm thickness increases with increasing heat treatment temperature(540-560℃)and time(1-6 h), and the maximum SH intensity among the samples studied is in the order of 1/10 in comparison with that of α-quartz single crystal. The transparent crystallized glass obtained by heat treatment at 550℃ for 3 h exhibits a clear and fine Maker fringe pattern, indicating a highly orientation of LiBGeO_4 crystals at the surface.

    The temperature dependence of Vickers hardness(H)of TeO_2-based glasses such as 15Na_2O・15ZnO・70TeO_2 as host glasses for rare-earth doped optical amplifier was measured from room temperature to the glass transition region. The following features were found ; (1)crack formation under the indenter easily occurs, the Vickers hardness at room temperature being around 3 GPa ; (2)the temperature coefficient of the hardness, dH/dT, is around -4.5×10^<-3>GPa・K^<-1> ; (3)the relative change of hardness with temperature is closely related to thermal expansion coefficient, and hardness sharply decreases in the glass transition region. It was demonstrated that TeO_2-based glasses are fragile even from the point of view of mechanical properties. The reason for poor mechanical performance in TeO_2-based glasses is their weak bond strength and open atomic packing structures. The hardness(H=4.8GPa)of a transparent glass-ceramic(with nanocrystalline particles)of 15K_2O・15Nb_2O_5・70TeO_2 showing second harmonic generation is much larger than that of the precursor glass(H=3.3 GPa), meaning that the improvement in the fragile character of TeO_2-based glasses is due to crystallization. A soda-lime silicate glass of 14Na_2O・13CaO・73SiO_2 has a value dH/dT=-6.5×10^<-3>GPa・K^<-1> and in contrast to TeO_2-based glasses, its hardness decrease in the glass transition region is gradual, and a value H&ap;2 GPa is obtained even at the glass transition temperature.

    本研究では,土壌に非放射性Csを添加し溶融することで,模擬汚染土壌をまず作製しておき,模擬汚染土壌に塩化物を溶融促進剤と共に添加し,低温で溶融処理することにより,塩化物相を揮発させるのではなく,固相で析出させ,Csを塩化物の固相に選択的に取り込ませることで土壌と分離し,Csを取り込んだ固相を水に溶解させ,その後イオン交換によりCsを分離回収するための処理プロセスの開発を目指している。
    まず先行研究の再現実験を試みた。MgCl2を添加した土壌を1100℃で溶融したが,土壌とは異なる白色の固形物が生成するものの,冷却後潮解してしまい,土壌と白色固形物を分離することができなかった。無水のMgCl2を用いたり,溶融促進剤として添加したLi2CO3の量や溶融温度を変更するなど,様々な条件を試みたものの,潮解することない安定な白色固形物を得ることができなかった。白色固形物は塩化物のはずなので,熱処理後の試料を水に浸漬し,塩化物相を溶解させることで土壌から分離することができると考えた。
    そこで,加熱処理後の試料が入った坩堝に水を注ぎ,その後流し出すことで土壌と水相を分離した。加熱処理前後の重量差から揮発量を,加熱後に坩堝に水を注ぎ,水を流し出した後乾燥し,坩堝に残った試料の重量を不溶性固体の量,加熱処理後の重量との重量差を可溶性固体の量とした。模擬汚染土壌とMgCl2の添加量を一定にし,Li2CO3添加量を変化させて加熱処理実験を行った。Li2CO3添加量の増加に伴い,不溶性固体量が増加したのに対して,可溶性固体量と揮発量はほぼ一定であった。
    今年度は,学内共同利用可能なICP装置がすべて故障していたため,不溶性固体と可溶性固体の組成分析を行うことができず,各相中のCs量を調べることができなかった。次年度は,利用可能な装置を探し,組成分析を行う予定である。

    ガラスの構造モデリングについて、はこれまで困難とされてきたB2O3系ガラスに取り組んだ。また、AXSデータや中性子のデータを併用した元素選択性のある構造データに基づいたモデリングを試みた。さらにBond Valence Sum(BVS)による拘束や第一原理計算を併用したモデリングを試みた。加えて、中性子や電子線を併用し、ガラス、アモルファス構造を多角的に捕らえることを試みた。
    これまで永久高密度化ガラスの構造を温度と圧力により操ることに成功したが、さらなる高圧下での試料合成を試みた。
    今回、圧力、温度をさらに検討し、世界一密度が高くかつ高密度のシリカ(SiO2)ガラスの合成に成功した。このガラスのX線回折データに現れる第一回折ピーク(First Sharp Diffraction Peak, FSDP)はこれまで報告されたどのガラスよりも鋭いものであることが確認できた。

    The non-radioactive Cs2CO3, PbO, CdO, and Cr2O3 were added to a commercially-available soil and melted at high temperatures to prepare a simulated contaminated soil. The melting conditions (container shape, melting temperature, and types of fluxes and chlorides added) were systematically varied to investigate the volatilization behavior of each element. The results showed that the volatilization rate of each element was higher in vessels with larger openings and at higher melting temperatures. Chlorides of MgCl2 or CaCl2 showed the highest volatilization rates. In the case of Cs volatilization, the addition of the flux was effective, but in the case of heavy metal elements, the addition of no flux resulted in higher volatilization rates.

    Anisotropic phosphate glasses were prepared by stress-induced deformation of isotropic ones at the glass transition region, and their structural anisotropy formed in the amorphous structure was investigated from the viewpoints of direction dependent characterizations, elastic moduli and birefringence, and structural analyses, XRD and polarized Raman techniques. Molecular dynamics simulation of anisotropic glass was performed for structural modeling and analysis, which revealed that metaphosphate glass was unique to show the feature of anisotropic orientation in both partial structures of phosphate chain and modifying cation.

    A large amount of phosphorus is contained in sewage sludge, and hence recovery of phosphorus from sewage sludge and recycling as phosphorous resources must be quite significant. This research group is working on the chemical recycling method of phosphorus contained in iron- and steel-making slags. Then, in the present project, the developing process has been applied to sewage sludge, and the possibility of phosphorus recovery from sewage sludge was examined. It was found that SiO2 addition was effective for the recovery of phosphorus, but the separation from the other constituents was quite difficult. It was finally suggested that melting under a reducing atmosphere was effective for the removal of ion, expecting the selective recovery of phosphorus.

    The precipitation morphologies and induced optical functions were evaluated for transparent glass-ceramic materials with a functional crystalline phase, fresnoite, and the parameters for both material and process have been optimized in terms of the efficiency of the optical functions. According to TEM observations, the transparent glass-ceramics with highly oriented fresnoite were consist of crystallites with sizes of 20-50 nm, and they primarily form highly oriented domains with various sizes> 200 nm, which would closely related to the novel crystallization mechanism for the crystal orientation together with the transparency in a bulk form.

    In the present study, we have focused on the reactivity between refractories and slags as a dominant factor for the slag corrosion resistance of refractories. It was revealed that the difference in Ols binding energy measured with X-ray photoelectron spectroscopy (XPS) was effective to estimate the reactivity. In the choice of material added to the refractory, candidate materials are explored based on the Ols binding energy, and the number of the candidates should be reduced based on the viscosity change after the reaction with slags.

    研究初年度において構築を完了した顕微分光学的手法による光学系を利用し、レーザー集光照射加熱法による局所的結晶化プロセスにおけるレーザー照射位置近傍の温度プロファイルおよび温度変化に関する計測を実施した。また、有限要素法に基づく伝熱モデルを改良し、計測結果に基づく温度プロファイルとの比較を行い、計測手法および伝熱モデルの相互検証から双方の妥当性に関する情報を得た。各々の概要は以下の通りである。
    半導体レーザー(波長808nm、最大出力1.20W)を熱源用レーザーとし、この波長域に吸収帯を有し熱源となるDr^<3+>イオンおよび蛍光スペクトルが温度指標となるEr^<3+>イオンをビスマスホウ酸系ガラス組成に対してそれぞれ9mol%、1mol%添加することによりモデル試料とした。Arイオンレーザー(波長488nm)励起による顕微蛍光スペクトル測定で蛍光帯のブランチ比を指標として、照射裏面の温度分布およびその経時変化を計測した。局所温度計測にあたり、顕微鏡用ホットステージを用いた試料全体加熱時の蛍光スペクトルを参照して温度を決定した。加熱点の最高到達温度はレーザー照射エネルギーおよび照射時間に依存し、ガラス転移温度、軟化温度、結晶化温度に達することを示し、従来提案の本プロセスにおける照射痕形成モデルを支持した。一方、有限要素法を用いた伝熱モデル計算では、上記のビスマスホウ酸系ガラスにおける熱物性値とエネルギー消失に関するより現実的モデル化への改良を加えた結果、最高到達温度および流動変形領域(軟化温度境界内部に相当)に関して実測に矛盾しない温度プロファイルを再現した。不連続境界の移動モデルの導入、高温物性値の考慮により、さらに現実的モデルとして高度化が期待されることが示唆された。

    ○レーザー誘起原子加熱法の適用によって、Li_2O-Nb_2O_3-SiO_2系ガラスにおいて強誘電性LiNbO_3結晶ラインのパターニング(Yb:YVO_4ファイバーレーザー:波長1080nm、パワー:1.3W、走査速度:7μm/s)を行い、偏光マイクロラマン散乱スペクトルおよび第二高調波強度の方位依存性(Azimuthal法)から、LiNbO_3結晶は単結晶に近い高配向(レーザー走査方向に沿ってc-軸配向)で成長していることを明らかにした。光導波(波長:632.8nm)実験の結果、LiNbO_3結晶ラインに有効に光が閉じ込められることを実証した。また、前駆体ガラスにEr_2O_3を添加することにより、結晶ラインから、Er^<3+>イオンに起因する蛍光が観測されたことから、LiNbO_3結晶にEr^<3+>が固溶することを明らかにした。光制御デバイス創製に大きく前進した。
    ○レーザー誘起原子加熱法によって、Gd_2O_3-MoO_3-B_2O_3系ガラスにおいて強弾性/強誘電性を示すβ'-Gd_2(MoO_4)_3結晶ラインは、屈折率の周期的構造およびそれに伴う第二高調波強度の周期的変化を示し、レーザー誘起結晶化において極めて特異な結晶成長をすることを発見した。また、前駆体ガラスを通常の電気炉で熱処理を行うと、結晶化に伴って、電気炉内(結晶化後の冷却過程ではなく)で自ら微粉化する現象を発見した。この現象を、我々は自己微粉化現象と命名した。自己微粉化したβ'-Gd_2(MoO_4)_3結晶片においても、屈折率の周期的構造およびそれに伴う第二高調波強度の周期的変化が観測された。これらの現象はいずれも、β'-Gd_2(MoO_4)_3結晶の強弾性に基づくものと結論した。新規光制御デバイスとしての可能性が高い。

    We succeeded in fabricating novel nano-crystalline particle structures on KNbO_3-TeO_2 glass induced by ultraviolet (UV) laser irradiation and found that the size and size distribution could be controlled by the conditions of laser irradiation, such as fluence, pulse repetition rate, and the temperature of the glass specimen by heat assistance (HA). Nano-sized crystalline particles are in interesting new material, because they will be able to open the door to the invention of photonic circuits of extremely small size, which transfer optical signals through optical near-field energy operating by a completely different principle. We have found two results from the experiment of UV laser irradiation with 308 nm wavelength as follows ; 1. the particle diameters are increased with increasing of the number of pulses, and then saturated up to approximately 30 J/cm^2. 2. When using HA with a glass specimen during laser irradiation, it has been found that the uniformity of particle size is markedly improved by HA treatment. The standard deviation of particle size is improved to be approximately 1/5. These results suggested that heat is involved in nanoparticle formation during UV laser irradiation, which means that the overall history of heating with pulsed laser irradiation is critically important to control the form of the particles, in other words, to make a tuning of crystallization/nucleation behaviors in glass.
    In addition, it should be noticed that nano-crystallization of rutile and anatase with 10 nm particle size was observed in CaO-B_2O_3-Bi_2O_3-Al_2O_3-TiO_2 glass systems. The color of the present crystallized glass was changed by the heat-treatment temperature, and X-ray diffraction (XRD) patterns of the crystallized glass show that the apparent color change is correlated with the formation of titania nano-crystallites. The present titania nano-crystallized glass will be not only a photocatalytic material but also a promising candidate for random lasing devices because of a large refractive index in titania.

    The purpose of the present study is to fabricate the patterning of crystal lines on the surface of glasses through the application of laser-induced crystallization techniques (i.e., samarium atom heat processing and transition metal atom heat processing) developed by our research group and to develop new optical functional devices. The following results were obtained.
    (1) In Sm_2O_3-Bi_2O_3-B_2O_3 based glasses, we succeeded in writing of curved and bending crystal lines showing second order optical nonlinearities by just changing the laser irradiation (continuous wave Nd:YAG laser with a wavelength of 1064 nm) direction. As the crystallographic direction of crystals in the lines was hold before and after the bending point and apparent light scattering was not observed at the bending point, it is proposed that the crystal lines patterned in this study can work as optical waveguides. Furthermore, it was clarified that the surface of crystal lines is smooth and any appreciable structural disorders are not present at the bending point.
    (2) A new laser-induced crystallization technique called "transition metal atom heat processing" instead of samarium atom heat processing was developed. In this new technique, a small amount (-1 mol%) of transition metal ions induces sufficient temperature increases in the laser-irradiated part, and various crystal lines such as LiNbO_3, Sr_<0.5>Ba_<0.5>Nb_2O_6,β'-Gd_2(MoO_4)_3, Ba_2TiGe_2O_8 were patterned successfully on the glass surfaces.
    (3) A new micro-fabrication technique on the glass surface using a combination of laser irradiation and chemical etching was proposed, and micro-channels with an inner diameter of 〜10μm were patterned on the surface of BaO-TiO_2-GeO_2 glasses. This technique would be applied for the patterning of electrodes at the vicinity of crystal lines.
    (4) We demonstrated that various crystal lines with optical nonlinear/ferroelectric functions are patterned by laser-induced crystallization techniques developed by us. This research would give a great impact in the science and technology of materials and functional devices.

    本研究は、光非線形性結晶化ガラス材料の探索と機能発現機構の解明を目指し、ガラスを熱処理あるいはレーザー照射局所加熱で得られる結晶化ガラスを対象に電気光学効果の確認と第2高調波顕微鏡(SHGM)下での非線形光学機能の評価を試みることを目的として以下の実験を行った。
    1.電気光学機能を有する透明結晶化ガラス
    研究初年度に引き続き、結晶化ガラスの組成および熱処理条件を再検討による透明性の向上を試みたが、結晶化ガラスにおいて測定に十分な透明性を維持したままで電気光学効果を見出すには至らなかった。また、プリズムカプラを用いた表面結晶層への光波導入に関しても結合が困難であることが明らかとなり、レーザー集光照射による光導波路型結晶化パターニングの実現を先行させる必要があると判断した。
    2.非線形光学結晶パターン形成とSHGM観察
    SHGMによる種々の結晶化ガラスの観察の結果、(1)BTG結晶化ガラスにおいて析出相の方位をSHGの偏光特性から特定した、(2)SiO_2:Ge薄膜の熱処理で得られる結晶化ガラスからのSHGは、析出するクリストバライト相近傍の残留応力の存在と関係することを明らかにした、(3)(Bi,Ln)BO_3系結晶化ガラスに析出する2相のうち非線形性の高いSHG活性相を特定した、(4)YAGレーザー照射によるβ-BBO相ラインパターニングにおける方位をSHGの偏光特性から特定した。
    3.SHGMによる非線形光学定数の定量
    z-cut石英を標準試料とし、非線形光学定数が既知であるニオブ酸リチウム(LN)単結晶試料のSHGM像の解析から、非線形光学定数の定量およびマッピングに関する一定の手法を確立し、BTG表面結晶化ガラスにおいて、析出結晶のd_33およびd_31が評価可能となった。これは、従来法のMakerフリンジ法による評価と比較しうるものであり、微細結晶での光学物性評価の可能性を見出した。

    The purpose of this project is to develop new technique for patterning of refractive index distribution in rare-earth tellurite glasses. Spatially selected dots and lines with refractive index changes or consisting of nonlinear optical crystals are fabricated in TeO_2-and Bi_2_3-based glasses by YAG laser irradiation. The following results were obtained.
    (1)The crystalline dots and lines consisting of the Sm_2Te_6O_15 phase were successfully written in Sm_2O_3-BaO-TeO_2 glasses by Nd:YAG laser(wavelength : 1064nm) irradiation, and the formation mechanism was clarified. In particular, it was found that the dots have the corn-type shape and grow from the surface to the interior. The size of dots increases with laser irradiation time t in the manner of t^<1/3>, indicating that the growth rate of crystalline dots is controlled by the diffusion of constituent ions.
    (2)The refractive index changes was successfully induced in the interior of Sm_2O_3-BaO-B_2O_3 glasses by the irradiation of nanosecond pulsed Nd:YAG laser. The line width of refractive index changes was 1〜13μm, and it changed with the laser power and laser focusing depth.
    (3)The curved crystal lines consisting of nonlinear optical crystals were constructed by changing the laser scanning direction, and the bending angle of curved lines was 0〜90°. It was confirmed from polarization optical microscope and polarized micro-Raman scattering spectra that the crystallographic direction of crystals in the lines was always constant, even though the crystal growth direction was changed. The writing of curved crystal lines in glass by laser irradiation technique in this study is the first report, and this success opens the door for the development of tunable optical waveguides.
    4)The crystal structure and phase transformation behavior of nonlinear optical crystals BiBO_3 and Sm_xBi_<1-x>BO_3 formed in Sm_2O_3-Bi_2O_3-B_2O_3 glasses were clarified from X-ray diffraction analyses and high temperature Raman scattering spectra. In particular, it was found that the BiBO_3 phase is stabilized through the incorporation of rare-earth ions into the crystal.

    The purpose of this project is to develop new short-wavelength solid-state lasers and optical amplification wave-guide by applying new transparent TeO_2, Bi_2O_3 and GeO_2-based crystallized glasses. The following results were obtained.
    (1) Transparent crystallized glasses (30BaO. 15TiO_2. 55GeO_2) with fresnoite-type Ba_2TiGe_2O_8 (BTG) crystals were fabricated, and it was clarified that BTG crystals show excellent second-order optical nonlinearities. In the crystallization process, firstly benitoite-type BaTiGe_3O_9 crystals are precipitated in the glass, and then BTG crystals are formed.
    (2) The second-order optical nonlinearities, i.e., d_<33> value, of LaBGeO_5, LiBGeO_4 and BTG crystallized glasses fabricated in this project were determined using Maker fringe method. Firstly, it was demonstrated that the d_<33> values estimated using crystallized glasses are almost consistent with the values of corresponding single crystals. It was discovered that BTG crystallized glasses exhibit largesecond-order optical nonlinearities of d_<33>- 22 pm/V, being comparable to the value of LiNbO_3 single crystals. The value of d_<33>-22 pm/V is the largest one in glass-related materials reported so far.
    (3) Other crystallized glasses with fresnoite-type Ba_2TiSi_2O_8 and Sr_2TiSi_2O_8 crystals were fabricated and the origin of large second-order optical nonlinearities in the fresnoite-type crystals was clarified. It was proposed that the spontaneous polarization of TiO_5 pyramidal units is enhanced by introducing Ba^<2+> and Ge^<4+> ions with large ionic radii.
    (4) It was demonstrated that transparent surface crystallized glasses with BTG crystals work as optical wave-guide. We propose that these crystallized glasses have a high potential for new short-wave length solid state lasers.
    (5) The writing of nonlinear optical single crystal-lines was succeeded through the irradiation of Nd:YAG laser operating at 1064 nm in TeO_2- and Bi_2O_3-based glasses. It was demonstrated that these crystals-lines works as optical wave-guides containing rare-earth ions.

    The purpose of this study is to clarify the mechanism of unique structural relaxation of optical functional TeOィイD22ィエD2- and BiィイD22ィエD2OィイD23ィエD2-based glasses with low phonon energies through measurements of viscosity, heat capacity and Vickers hardness in the glass transition region. The following results were obtained.
    1) the thermal stability against crystallization in RィイD22ィエD20-MO-TeOィイD22ィエD2 glasses (R=Li,Na, K, M=Mg, Ba, Zn) increases with the combination between oxides showing large different optical basicities ( e.g. KィイD22ィエD2O-MgO, LiィイD22ィエD20-BaO).
    2) the heat capacity changes at the glass transition in KィイD22ィエD20-MgO-TeOィイD22ィエD2 glasses are extremely large, I.e. ΔCィイD2PィエD2A=45J/molK, meaning that the breaking of the network structure and rearrangements among network units occur easily in these glasses. This feature is appeared in a rapid decrease of Vickers hardness at the glass transition.
    3) the activation energies for enthalpy relaxation in TeOィイD22ィエD2-based glasses are 900〜1250kJ/mo, which are much large compared with silicate glasses, and those for viscous flow are 500〜750kJ/mol, giving the fragility values of around 60. The decoupling between enthalpy relaxation and viscous flow is clearly observed in both TeOィイD22ィエD2- and BiィイD22ィエD2OィイD23ィエD2-based (such as BiィイD22ィエD20ィイD23ィエD2-BィイD22ィエD20ィイD23ィエD2) glasses.
    4) both TeOィイD22ィエD2- and BiィイD22ィエD2OィイD23ィエD2-based glasses belong to the category of fragile glass-forming systems.
    5) both systems show a unique structural relaxation at the glass transition, but the present study demonstrates that it is possible to fabricate glasses having high potential for technical applications.

    ガラスは、本来、反転対称性を有することから、2次非線形現象である第2高調波発生(SHG)を示さないが、熱あるいは光による励起を伴った高電場処理により反転対称性を失った状態を誘起、凍結したガラスからSHGが見出されており、熱ポーリング、紫外光ポーリングなどと呼ばれる。本研究は、酸化物ガラスの熱高電場処理過程におけるイオンの動き、ガラス構造の変化、結果として生じるSHG等の現象の関連に着目し、これらの過程におけるダイナミックスを解明することを目的とした。
    熱ポーリング過程の変化をSHG測定により捉えるため、Nd:YAGレーザー、分光検出器、高電圧電源、ファンクションジェネレーター等から構成される装置を構築した。高電圧直流電源を制御することにより、平板状ガラス試料に周期的な電場(V_<pp>=1-3kV,10mHz)を印加し、同時にMakerフリンジ法によるSHG測定を可能にした。YAGレーザー入射と電場方向の配置について検討した結果、電場に対して垂直な入射方向の場合に、明瞭なフリンジが周期電場に応答することを確認した。当初、市販のソーダライムガラスおよび無アルカリガラス7059(双方とも厚さ約1mm)を試料とすることにより、最適な測定の条件を設定できたが、比較的大きな非線形性が期待できるテルライト系、ビスマス系の酸化物ガラスについては、試料の加工性に問題が生じ、市販ガラスと同様の条件での測定は実現できなかった。ポーリング処理したガラスの表面に微結晶が析出し、SHG活性に寄与することが報告されている。試料表面での電荷層の形成や局所的な構造変化をとらえる目的では、本研究で採用した測定手法に特に問題がないが、結晶化をはじめ不可逆な現象が関与する場合、本装置による測定時間、シグナル強度などに再検討を必要とすることが指摘された。

    光を最大限に利用でき、かつ光の制御を可能にする新しい光学的傾斜機能材料、あるいは光エネルギーを電気エネルギーに効率よく変換できる従来にないタイプの光電的傾斜機能材料の開発は今後ますます重要になる。本研究は、第二高調波発生(非線形性)を示す光学的に透明な結晶化相と非線形性を示さないガラス相の割合いが傾斜した構造を有する光学的線形・非線形傾斜機能型透明テルライト系ガラスセラミックスの創製を試み、次の成果を得た。
    1)15K2O-15Nb2O5-70TeO2ガラスのNb^<5+>をW^<6+>やMo^<6+>で置換したガラスは、結晶化に対して著しく安定になることから、15K2O-15Nb2O5-70TeO2ガラスと接合するガラス系として選択した。2)15K2O-15Nb2O5-70TeO2ガラスにEr^<3+>を添加した系では、Er2O3を1.5mol%まで添加しても透明ガラスセラミックスが得られることが明らかになった。3)ガラス表面での結晶化相はバルス内部とはかなり異なった状態になっており、内部に比べて非常に大きなSHGを示すことを発見した。4)15K2O-15Nb2O5-70TeO_2ガラスと15K2O-15W2O6-70TeO2ガラスの接合体は、2種類のガラス融液をアルミナボ-トに順次流し出す手法により作製した。ガラス同志の接合は十分に起こったが、熱処理するとガラス相と結晶化相の界面にクラックが生じた。これは、15K2O-15W2O6-70TeO2ガラスと15K2O-15Nb2O6-70TeO2透明ガラスセラミックスの熱膨張係数が大きく異なるためと推察された。また、アルカリ金属イオンの場合と違って、テルライト系ガラス中におけるNb^<5+>とW^<6+>の相互拡散はかなり起こりずらいことが明らかになり、本研究の目的を達成させるためには、もう少し拡散しやすい化学種、例えば、アルカリ土類金属イオンなどを含んだ安定なガラス系を利用する必要があることがわかった。

    The purpose of the present study is to clarify the mechanism of the second harmoinic generation (SHG) in transparent tellurite-based glass-ceramics which have been discovered by the present author's group. The following results were obtained. 1) The chemical composition of the crystalline phase showing SHG in 15K_2O-15Nb_2O_5-70TeO_2 glass-ceramics corresponds to K (Nb_<1/3>Te_<2/3>) _2O_<4.8> approximately, and its crystal structure is oxygen-defect fluorite type. This crystal is distorted slightly from cubic, maybe causing SHG.2) The lattice constant of the crystalline phase in xNa_2O- (15-x) K_2O-15Nb_2O_5-70TeO_2 glass-ceramics decreases linearly with increasing Na_2O content, meaning the appearance of the solid solution between Na^+and K^+. The intensity of SHG decreases steeply with increasing Na_2O/K_2O ratio, and the glass-ceramic with x=8 shows no SHG.3) The thermal stability against crystallaization in 15K_2O-xRO- (15-x) Nb_2O_5-70TeO_2, RO=WO_3, MoO_3, is extremely high, and the formation of the crystalline phase showing SHG tend to be difficult. 4) The surface crystallization layr generates strong second harmonic generation compared with the interior of the glass-ceramics. 5) The transparent Er^<3+>-doped tellurite-based glass-ceramics have been fabricated, and the upconversion at 550nm due to ^4S_<3/2>*^4I_<15/2> transition under the irradiation of laser with 800nm wavelength is clearly observed. 6) It is found from heat capacity changes at the glass transition that rearrangements among structural units occurs easily in tellurite-based glasses.

    光を最大限に利用でき、かつ光の制御を可能にする新しい光学的傾斜機能材料、あるいは光エネルギーを電気エネルギーに効率よく変換できる従来にないタイプの光電的傾斜機能材料の開発は今後ますます重要になる。我々は、第二高調波発生を示す光学的に非線形な透明なテルライト系ガラスセラミックス(母体ガラスの組成:15K_2O-15Nb_2O_5-70TeO_2)を発見し、しかも、非線形性の発現は母体ガラスのアルカリ金属イオンの種類に大きく依存することを見出した。すなわち、アルカリ金属イオンの分布を傾斜化することにより、これまで全く発想されることのなかった光学的に線形・非線形な透明な傾斜機能型ガラスセラミックスの創製ができることになる。
    本研究で得られた成果は次の通りである。1)xNa_2O-(15-x)K_2O-15Nb_2O_5-70TeO_2系の透明ガラスセラミックスの作製を試み、x=0〜8の組成範囲で透明なガラスセラミックスを得た。格子定数の測定から、生成する結晶相においてNa^+とK^+はお互いに全率固溶することが明らかになり、アルカリ金属イオンの組成分布を傾斜化することが可能であることを示した。また、透明ガラスセラミックスの誘電率、熱膨張係数などの物性がNa_2O/K_2O比によって連続的に変化することを明らかにした。2)アルカリ金属イオンが異なる2種類のガラスを高温で接合した後、2段階熱処理することにより透明かつ接合界面近傍でアルカリ金属イオンが傾斜したガラスセラミックスを作製した。3)ガラスセラミックスから発生する第二高調波の強度の測定装置を組立てた。Na_2O/K_2O比と共に第二高調波の強度が急激に小さくなり、特に、x=8の試料では第二高調波の発生は確認できなかった。本研究は、透明な傾斜型ガラスセラミックスの創製が可能であることを初めて実証すると共に、デバイス等への応用が大いに期待できる新規な光機能傾斜型材料であることを明らかにした。
