Abstract

The influence of γ-irradiation on optical properties of the pseudobinary "stoichiometric" Sb₂S₃-GeS₂ and the non-stoichiometric Sb₂S₃-Ge₂S₃ chalcogenide glasses (ChG) prepared by a standard melt-quenching method is studied. It is established that in the case of the both investigated cut-sections the "γ-darkening" effect (i.e. the "red" shift of the fundamental optical absorption edge), consisting the dynamic (relaxing with time) and the static (remaining constant approximately two months after irradiation) components, takes place. The comparison of compositional trend of the "γ-darkening" effect for the pseudobinary and the non-stoichiometric investigated ChG is made. Phenomenological description of the observed effects is carried out taking the degree of chemical bond metallization, concentration of chemical bonds and free volume parameters into consideration.
