  absorb peak
    The adsorption of BATE by Al_2O_3 makes the 1360cm-1 absorb peak of BATE didived into two absorb peaks (1409cm-1 and 1287cm-1) and the 1036cm-1 absorb peak shifted to 1067cm-1. Under low pressure the height of the absorb peaks is direct proportion to the pressure of BATE and to the Al_2O_3 content.

The absorption and luminescence spectra of Ce-doped silica glass are studied, and theeffect of γ-ray radiation on the glass is discussed in this paper.The results obtained are asfollows: (1) In silica glass,the basic valence state of cerium is Ce~(3+),its absorption peak lyingat 320 nm. The relationship between absorption and concentration in the glass obeys Beer'slaw.The cerous ion yields an intensive blue fluorescence under near UV excitation. (2) When the glass is treated in O_2 or H_2 atmosphere at transition...

The relationship between absorption and concentration in the glass obeys Beer'slaw.The cerous ion yields an intensive blue fluorescence under near UV excitation. (2) When the glass is treated in O_2 or H_2 atmosphere at transition temperature T_0,a revelsible change takes place between the cerous and ceric ions.The ceric ion exists insilica glass melted in the O_2-enriched flame or by oxidation treatment.It has an intenseand broad absorption band in the UV range, its peak value lying at 260 nm, as is seldomdetected in most glasses. (3) The adoption of cerium to silica glass increases its stability under γ-ray radiationand leads to shift of the color center from the visible region to the UV region in the spec-trum.

本文研究了掺铈石英玻璃的光谱吸收和发光光谱,同时讨论了玻璃的γ射线辐照效应。获得如下结果: (1)在石英玻璃中铈离子的基本价态为Ce~(3+),吸收峰位于320nm处,吸收和浓度符合比耳定律。在近紫外光激发下Ce~(3+)离子产生强烈的蓝色荧光。 (2)玻璃在转变温度(T_g)下、在氢或氧气氛中热处理时,Ce~(3+)离子和Ce~(4+)离子之间发生可逆变化。高价铈离子存在于富氧火焰熔制和氧化处理的玻璃中,在紫外区具有强烈而宽阔的吸收带,峰值位于260nm处,这在大多数玻璃中是难于发现的。 (3)铈的掺入提高了石英玻璃的γ射线辐照稳定性,使得“色心”从光谱可见区移向紫外区。

The effect of oxide impurity on the physical properties of 62 ZrF4-8 LaF3-30 BaF2 (mol %) glass was studied by equimolecular substitution of BaO for BaF2. It is shown that oxide impurity decreases the infrared transparency beyond 6μm, lead to an additional absorption band at 1350 cm-1, and increases the glass transition temperature, the crystallization temperature and the viscosity of glass. The additional infrared absorption of oxide impurity in the fluorozirconate glasses result from the multiphonon process...

The effect of oxide impurity on the physical properties of 62 ZrF4-8 LaF3-30 BaF2 (mol %) glass was studied by equimolecular substitution of BaO for BaF2. It is shown that oxide impurity decreases the infrared transparency beyond 6μm, lead to an additional absorption band at 1350 cm-1, and increases the glass transition temperature, the crystallization temperature and the viscosity of glass. The additional infrared absorption of oxide impurity in the fluorozirconate glasses result from the multiphonon process of the vibration of F-Zr-O bonds at 680 cm-1.

用BaO等分子取代BaF_2的方法研究了氧化物杂质对62ZrF_4·8LaE3·32BaF_2(mol%)玻璃物理性质的影响.结果表明,杂质氧化物的存在使玻璃在6μm以后的红外透过率下降,在1350cm~(-1)附近产生附加吸收峰,使并玻璃的转变温度、析晶开始温度和粘度升高.杂质氧化物在氟锆酸盐玻璃中引起的附加吸收是由F—Zr—O键在680cm~(-1)处振动的多声子过程所引起.

The relationship between the structure and composition of glasses in the systemNa_2O-B_2O_3-SiO_2 has been studied by measuring optical absorption and ESR of Cu~(2+).It isfound that, when B_2O_3 content is about 25 mol%,there is an abrupt change on the g_1 curveand a minimum value appears on the A_1 curve,and so does the peak energy of opticalabsorption.Moreover, these parameters vary markedly when the ratio of sodium oxide toboron oxide is less than 0.5.Such variation is related to the structural changes of...

本文运用Cu~(2+)在玻璃中的吸收光谱与顺磁共振谱研究了 Na_2O-B_2O_3-SiO_2 玻璃的结构与组成的关系。获了得在 B_2O_3含量为 25mol%附近g_1 因子有一转折,而在A_1 及光吸收峰的能量的变化曲线上则呈现极小值。此外,当Na_2O 与B_2O_3 的比例小于0.5时,这些参数的变化比较显著。上述变化是与玻璃结构内不同硼氧和硅氧基团的变化有关。
