The experimental results on time dependent changes of radiation-induced darkening effects in vitreous chalcogenide semiconductors of ternary stoichiometric (As2S3)y(GeS2)t-y and non-stoichiometric (As2S3)x(Ge2S3)t-x systems with variations of the average coordination number Z are discussed. We established that an adequate model for the quantitative description of these effects can be developed on the basis of bimolecular relaxation function appropriate for annihilation of specific structural defects in the form of oppositely charged atoms with anomal coordinations. The observed features of the investigated dynamic radiation-optical changes in these glasses are explained by their compositional dependences on atomic compactness, as well as covalent bond statistics.
