Abstract

The aim of the work is to investigate the optimum conditions of preparing CdS1-xSex conventional materials with high crystallinity and strong photoluminescence. Various techniques are employed to characterize the CdS1-xSex conventional materials. Results indicate that the composition, structure, and photoluminescence of the CdS1-xSex strongly depend on the reaction temperature, pH of reaction medium, and CS(NH2)2/CdCl2 molar ratio. For the CdS1-xSex conventional materials with high crystallinity and strong photoluminescence, the optimum reaction temperature, pH of reaction medium, and CS(NH2)2/CdCl2 molar ratio, are 150 °C, 12.01, and 5–10, respectively. Basing on these results, the mechanism of the CdS1-xSex production is proposed.
