| Abstract: | The homogeneous glass sample for the (1-x)As 2S 3-xCdBr 2,where x=0.015,0.035, 0.05, was prepared by the conventional melt-quenched method.Amorphous (1-x)As 2S 3-xCdBr 2 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 CdBr 2. Based on the experimental data, the microstructure is considered to be the discrete molecule species of AsBr 3 and Cd-S atomic bonds or clusters are homogeneously dispersed in a disordered polymer network formed by AsS 3 pyramids interlinked by sulfur bridges. |
