摘要：

The glass-forming region in the GeS2-Ga-I system has been determined and its limits are 32 at.% Ga and 60 at.% I. The basic physicochemical parameters (glass transition temperature, density and microhardness) of the glasses have been measured. They are transmitting in the mid IR-region up to approximately 20 mum. A photobleaching effect in thin films has been observed, and a reversible shift of the optical absorption edge after combined treatment by thermal annealing and ultraviolet exposure has been established.
