摘要

我们建议应用热激活光谱法来研究杂质的光学吸收问题。该方法包括测量宽间隙半导体晶体中光吸收的温度依赖性，并分析这种依赖性的温度导数。上述技术可以确定杂质中心的热活化和光活化的能量以及电子-声子相互作用的强度。

Thermally activated spectroscopy of optical absorption in Bi12SiO20 crystals

We suggest applying a method of thermally activated spectroscopy to the problem of impurity optical absorption. The method consists in measuring the temperature dependence of optical absorption in a wide-gap semiconductor crystal and analyzing the temperature derivative of this dependence. The above technique allows for determining the energies of thermal and optical activations and the strength of electron–phonon interaction for the impurity centres.
