Paper Abstract

A systematic investigation of the Ag x -Sb 2 (1-x) -Te 3 (1-x) (x=0.16, 0.18 and 0.20) is reported. The alloy of Ag-Sb-Te glass system, obtained by rapid quenching technique has been characterized by calorimetric measurements and differential thermal analysis (DTA) for different heating rates. The optical properties of the material were studied using UV spectrophotometer. The optical band gap (E o) was estimated for these samples by measuring absorption coefficient as a function of wavelength of light in the range 300 -900 nm. The films of the different compositions of Ag were studied for both the cases of before and after annealing. The present study is an attempt to understand the effect of alloying Ag into amorphous Te chalcogenide glasses.
