Effect of Alcohol Solvent on Morphology and Properties of N,N′-(2,4-Dichlorophenyl)Thiourea/CdS Nanocomposites

The nanocomposites of N,N′-(2,4-dichlorophenyl)thiourea/CdS were successfully synthesized in the different mixture of water and alcohol by lipuid in situ precipitation method.The morphology and optical properties of products were characterized by scanning electron microscope(SEM),X-ray diffraction(XRD),FTIR spectroscopy,UV-Vis spectroscopy,fluorescence spectrum(PL).The morphology and properties of the CdS nanocomposites were effected by change of the alcohol viscosity.Long nanorods were obtained in low viscous alcohols,while solid spheres with surface of conical-burr were obtained in high viscous triethanolamine.
