本文研究、总结了硫硒碲化镉着色玻璃光吸收性质的基本规律,得到了一些新结果:(1)玻璃的光吸收限不但与相应半导体的禁带宽度一致,且它们的温度系数也具有同样的符号相近的数值.(2)在不同温度下玻璃的光吸收系数(α)与光子能量(E)成指数关系,在光子能量固定时吸收系数与温度以(T)成指数关系.α、E、T间的关系可以写成经验式α=α0exp(AE+BT).式中,α0、A、B为常数.

The fundmental regularities of governing the optical absorption properties of glasses colored with Cd(S, Se, Te) have been investigated and summarized. Some new results are obtained. (1) The absorption edge of the glass agrees with the energy gap of the corresponding semiconductor, and their temperature coefficients have the same sign and similar values. (2) The absorption coefficient (α) depends exponentially on the photon energy (E) at different temperatures, and on the temperature (T) at constant value of the photon energy. The relationship among them may be written as an empirical formular α=α0exip(AE+BT), where α0, A and B are constants.
