Abstract
This paper reports on the results of investigations into the radiation stability of tin charge states in the (As2Se3)1−z (SnSe) z − x (GeSe) x glasses. It is revealed using 119Sn Mössbauer spectroscopy that gamma irradiation of the (As2Se3)1−z (SnSe) z − x (GeSe) x glasses leads to partial oxidation of doubly charged tin ions with the formation of the amorphous (finely dispersed) SnO2 phase blocked by the glass. As a result, the physicochemical properties (density, microhardness, glass transition temperature, activation energy for electrical conduction) of the glasses exposed to gamma irradiation remain virtually unchanged.
