Formation and properties of chalcogenide glasses based on GeS2-​Sb2S3-​AgI system

Abstract : Novel glasses in GeS2-​Sb2S3-​AgI system have been prepd. by melt-​quenching method. A large glass-​forming region was found in this novel system, in which almost 60 mol​% AgI has been incorporated. The basic physiochem. properties of glass samples were investigated. With the addn. of AgI, red shift of short-​wavelength absorption edge and distinct drop of the glass transition temp. (Tg) were obsd. In addn., a high Ag+ ion cond. of 6.37×10-​4 S​/cm at room temp. was obtained in 55(0.6GeS2-​0.4Sb2S3)​-​45AgI sample, indicating that these glasses have potential application as amorphous solid electrolytes.
