Synthesis and Characterization of CdS Nanoparticles

Abstract:

CdS nanoparticles were synthesized by using PVP (polyvinylpyrrolidone) as macromolecular surfactant, N, N-dimethylformamide as solvent, cadmium acetate and thiourea as precursors. The optical properties and morphologies for the synthesized CdS nanoparticles were characterized by UV-Vis absorption spectroscopy and TEM (transmission electron microscopy) measurements. The results show that PVP could act as a better stabilizer for the formation of CdS nanoparticles in N, N-dimethylformamide. The obtained CdS nanoparticles have spherical morphology and a narrow size distribution. CdS nanoparticles could give an apparent extionic absorption peaks and quantum confinement effects.
