Temperature dependence of optical transmission in fundamental optical absorption edge region is studied for typical representative of stoichiometric Sb2S3-GeS2 glasses. It is shown that this temperature behavior changes after Co60 gamma-irradiation. The observed effect is associated with Ge-S into S-S covalent bonds switching accompanied by coordination defects formation processes. This radiation-induced optical effect is fully reversible and could be erased by the annealing of the samples below transition temperature.
