卤化银光色玻璃中 R^(++)置换 R^+对 f(Ts)的影响

Effects of the Replacement of R^+ with R^(++)in AgX Photochromic Glass on f(Ts)

本文运用 X 射线小角散射方法研究 AgX 光色玻璃的亚微观结构,用自建的光色参数测试仪测定了光色玻璃在不同环境温度下的饱和变暗透过率。定量地描述了不同 R^(++)离子取代 R^+离子后,玻璃中含 AgX 微晶液滴尺寸的粒度大小及分布变化与光色玻璃饱和变暗度温度系数 f(T_(?))间的关系,为改善光色玻璃的实用性提供了理论依据。

The submicroscopic structure of AgX photochromic glass was studied by thesmall-angle X-ray scattering method.The saturated darkening transmittance in dif-ferent enviroment temperatures was measured by using the self-made photochromicparameter instrument.The quantitative description of the relation between tempera-ture coefficient f(T_(?)) of saturated darkening degree and grain size and distributionof the droplets containing AgX microcrystalline after the replacement of R^+ with R^(++)was given.The theoretic basis for improving the practicability of photochromic glasswas provided.
