Synthesis and Characterization of Pure Zinc Oxide Nanoparticles by Precipitation Method

We synthesized zinc oxide nanoparticles by precipitation method using zinc sulfate and sodium hydroxide as raw materials. The synthesized zinc oxide nanoparticles were characterized by X-Ray Diffraction (XRD) and UV spectroscopy to obtain crystal morphology and its optical properties. By XRD analysis, we obtained pure structure of zinc oxide nanoparticles and average size was found to be 27.65 nm. We obtained pure wurtzite hexagonal structure of zinc oxide nanoparticles by XRD having lattice parameters a=b= 3.2490 and c= 5.2070. UV absorption studies were carried out to obtain the optical properties of synthesized particles. The maximum absorbance was observed at 330 nm.
