Microstructure and thermal properties of (1−x) As₂S₃−xCdCl₂ glassy system

Abstract

The homogenous glass samples of the (1−x) As₂S₃−xCdCl₂ where x=0 and 0.05 were prepared by the conventional melt-quenched method. The addition of 5 mol% CdCl₂ enhanced the glass transition temperature of pure As₂S₃ glass sample by about 30°C. Based on the experimental data, the microstructure is considered to be that the discrete molecule species of AsCl₃ and nanocrystal CdS is homogeneously dispersed in the disordered polymer network formed by AsS₃ pyramids interconnected by sulfur bridges.
