| Abstract | Zinc oxide nanoparticles (ZnO-NPs) have been grown by simple chemical precipitation method using Zinc nitrate hexa hydrate [Zn (NO3)2 .6H2O] and sodium hydroxide (NaOH) in the molar ratio 1:2 as source materials. Polyvinyl Pyrrolidone (PVP) is used as the capping agent in the synthesis of ZnO-NPs. The reaction temperature is maintained at 60C during the growth process. The as-grown ZnONPs have been investigated by X-ray Diffraction (XRD) study, Scanning Electron Microscopy (SEM), Ultra Violet-Visible (UV-Vis) absorption spectroscopy and Photoluminescence (PL) spectroscopy respectively. The XRD result reveals that as-grown ZnO-NPs exhibit good crystallinity with hexagonal wurtzite crystal structure and the average crystallite size calculated from XRD pattern is found to be 15nm. The SEM image shows that the grown ZnO-NPs are nearly spherical in shape with slight agglomeration. The UV-Vis absorption spectrum exhibits a blue shift in wavelength as compared to bulk ZnO and the PL spectrum shows strong emission in the UV range with the excitation wavelength 320nm. |
