摘要：

We investigate photostructural transformations in glassy Ge–S films by the method of luminescence and Raman scattering of light. The appearance of a new shortwave band in the luminescence spectra of sulfur‐enriched Ge–S specimens as a result of irradiation by a He–Cd‐laser light and subsequent relaxation is discussed. To explain the results obtained, a model of photostructural transformations is invoked, in which the decisive role is assigned to solitary electrons of the chalcogen atoms.
