Synthesis of Sphere-Like CdS Cluster-shaped Structure by Microwave Hydrothermal Process
摘要
Abstract
CdS microcrystaUine with a sphere-like cluster-shaped structure was prepared with cadmium acetate (Cd(CH3COO)2.2H2O) and sodium thiosulfate (Na2S2O3) as raw materials by a microwave hydrothermal process. The influences of microwave hydrothermal temperature and time, and S/Cd mole ratio on the phase composition and morphologies of the product were investigated. The optical property of the sphere-like cluster-shaped CdS crystallites was analyzed. The results indicate that the CdS microcrystalline prepared with cadmium acetate as a cadmium source obtains the special morphology of sphere-like cluster-shaped structure. The CHHCOO- played a template role in the formation process of the sphere-like cluster-shaped CdS crystalline.The crystallization and grain size of CdS microcrystalline increased gradually with increasing hydrothermal temperature and reaction time. The morphology of prepared CdS transformed from sphere-like cluster-shaped structure to quasi-sphere shaped structure when S/Cd molar ratio increased. Ac- cording to the analysis of the ultraviolet-visible absorption spectra, the CdS samples had a strong absorption in visible region with an obvious red shift.关键词
