Microstructure and thermal properties analysis of (1−x) As₂S₃−xCdBr₂ glass system

Abstract

The homogeneous glass sample for the (1−x)As₂S₃−xCdBr₂, where x=0.015, 0.035, 0.05, was prepared by the conventional melt-quenched method. Amorphous (1−x)As₂S₃−xCdBr₂ alloys were determined by X-ray diffraction, thermal comprehensive analysis and Raman scattering. The glass transition temperature (T_g) decreases a bit with the addition of CdBr₂. Based on the experimental data, the microstructure is considered to be the discrete molecule species of AsBr₃ and Cd−S atomic bonds or clusters are homogeneously dispersed in a disordered polymer network formed by AsS₃ pyramids interlinked by sulfur bridges.
