Abstract
Synthesis of Zincoxide nanoparticles (ZnO NPs) with definite size and shape and their morphological characterization rationally is really a challenging aspect at present due to the ongoing demand of these nanosize particles for their divergent use in different field of science and technology. Reduction of Zinc acetate dihydrate by sodium hydroxide was performed to produce ZnO NPs by following precipitation method. Here the whole reaction was completed in aqueous medium in low temperature. To characterize the synthesized ZnO NPs some recent techniques like X-ray diffraction study (XRD), Ultra-violet Visible (UV-Vis) spectroscopy, Field emission scanning electron microscopy (FESEM), Transmission electron microscopy (TEM), Selected area electron diffraction (SAED) and Electron diffraction X-ray (EDX) were used systematically.
