Correlation between physical, thermal and optical properties of Ge-Se-Sb chalcogenide glasses

In this paper we have analysed the thermal, physical and optical properties of three different compositions of Chalcogenide glasses ie Ge20Se70Sb10, Ge25Se65Sb10 and Ge30Se60Sb10 glasses. The compositional dependence on properties were studied using absorption measurements, Differential Scanning Calorimetry (DSC) analysis and FTIR analysis by varying atomic % of Ge with respect to Se keeping Sb constant. Studies prove these materials to be promising candidates for the development of tunable optical devices for optoelectronic applications.
