Abstract
Now a day the more interesting and attracting point in research area is synthesis of nanoparticles with specific properties. Due to unique properties of oxide of nanoparticles achieve great attention in research areas. It is widely used as solar energy conversion, catalysis, varistors, gas sensors, non linear optics etc. ZnO nanostructures obtained a great attention in the research area because ZnO has large band gap. There are many different methods for synthesis of ZnO nanoparticles such as sol-gel method, chemical vapor decomposition, thermal decomposition, hydrothermal method etc. Among this method sol-gel method is the best for the preparation of ZnO nanoparticle. Fabrication of nanomaterial by sol gel method is simple and also its have advantage to control the size of material and morphology study of the material. The main objective of this paper is synthesis of ZnO nanoparticle by sol-gel method and studies its characterization. In this zinc acetate used as precursor, methanol as solvent, NaOH used as medium. The obtained ZnO nanoparticles are homogeneous and consistent in size corresponds to the XRD result that exhibit good crystallinity .ZnO nanoparticles are successfully synthesized by sol gel method. The obtained ZnO nanoparticles are characterized by XRD, SEM, and UV-visible
