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