In this study, zinc oxide nanoparticles were produced using a special method (co-precipitation), which had a hexagonal shape, in which zinc acetate serving as a starting material. The structure and optical characteristic were examined using technique X-ray diffraction (XRD), IR spectroscopy, and UV-Visible absorption spectroscopy. The XRD analysis confirm the formation of zinc oxide (ZnO) particles and via Scherrer equation lattice parameters and average crystallite size was find out. Furthermore, the dielectric properties like permittivity and dielectric loss of ZnO were analyzed by different frequencies and temperature to understand the potential of electronic application of Zinc Oxide.
