Zinc oxide (ZnO) nanoparticles have been prepared by chemical synthesis method. The powder was characterized by X-ray diffraction, UV-Vis optical absorption and photoluminescence spectroscopy analysis. XRD patterns showed that ZnO nanoparticles have hexagonal unit cell structure. An excitonic absorption peak is observed at 450 nm in UV-Vis absorption spectrum. The photoluminescence spectrum exibits emission peak located at 520 nm which is due to presence of singly ionized oxygen vacancies.
