Description
Summary:The Zinc oxide (ZnO) and cadmium sulfide (CdS) nanostructures and ZnO/CdS nanocomposite were prepared by a solvothermal method using acetate precursors using 1:1 volume mixture of water and ethanol as solvent. The structural characterization of the synthesized samples was carried by X-ray diffraction (XRD) technique and the results showed hexagonal and cubic phases for ZnO and CdS, respectively. The surface morphology and elemental compositions were analyzed using FESEM and EDX spectroscopy. The optical absorption and photoluminescence properties were characterized by UV-Visible absorption spectroscopy and photoluminescence spectrometer (PL), respectively. ZnO/CdS nanocomposite shows an enhanced optical absorption with respect to the ZnO and CdS nanostructures. ZnO nanostructures show an intense band edge luminescence.
