Paper Abstract

The photoinduced changes of optical constants in As2S3 films were experimentally studied according to the wave length of initiating radiation at different exposure temperatures. It was determined that the irradiation leads not only to shift but also to change in a slope of the Urbach absorption margin. It was shown that the basic experimental relationships describing the photoinduced changes of optical constants conform with a model of heterogenous medium with a local heating of microareas.
