Annotation A simple mechanical alloying technique for the synthesis of ZnO-CdS powder nanocomposite is reported. Structural and optical properties of ZnO-CdS powder nanocomposite have been evaluated by suitable characterization techniques. The X-ray diffraction spectrum contains a series of peaks corresponding to reflections from various sets of lattice planes of hexagonal ZnO as well as hexagonal CdS. In UV-Vis absorption spectra, two different absorption peaks were observed. The room temperature photoluminescence spectrum of the ZnO-CdS powder nanocomposites has two emission bands: an ultraviolet emission peak at 365 nm and a green emission around 510 nm. FTIR spectroscopy confirmed the presence of Zn-O bond and Cd-S bond.
