Zinc oxide nanoparticles were synthesized via precipitation method after annealing the precursor at different temperatures. The effects of annealing temperatures for the precursors on the particle size of ZnO NPs were investigated. The structure and composition of the precursor and prepared ZnO NPs were studied using X-ray diffraction (XRD), Scanning electron microscopy (SEM), Transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR) and thermal gravimetric analysis (TGA). The optical properties of the ZnO NPs were characterized using UV-visible spectroscopy. The XRD results revealed that the ZnO NPs are highly crystalline, having the hexagonal wurtzite crystal structure. The SEM images showed that ZnO nanoparticles prepared in this study were spherical in shape. The results of the UV-vis studies showed that the optical properties of the ZnO NPs depended on the annealing temperature. The size of ZnO NPs increased with an increase in annealing temperature.
