Solvothermal synthesis of nanocrystalline cadmium sulfide

The synthesis of CdS nanoparticles was widely studied for their potential u sage in the field of optics. The solvothermal synthesis with ethylene glyco l as the solvent was studied in this paper. The cadmium acetate and thioace tamide were used as the cadmium source and sulfide source. It was observed under TEM that the crystallites are almost spherical. The x-ray and electro n diffraction results show that the CdS nanocrystallites belong to cubic ph ase. The sizes of the crystallites were determined by XRD and UV absorption to be 4 to 9 nm depending on the amount and molar ratio of the reactants. The photoluminescence properties of CdS nanocrystallites in solution and in solid state were investigated. (C) 2000 Kluwer Academic Publishers.
