Description :
In the present study, Zinc oxide nanoparticles were synthesized using a simple sol-gel method, with zinc chloride, zinc nitrate and sodium hydroxide as starting materials at room temperature. The synthesized ZnO nanoparticles were then characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), UV-Visible spectroscopy. SEM images show hexagonal morphological of ZnO obtained, with average crystallite size of the sample below 100 nm. Which were calculated from the full width at half maximum of XRD peaks by using Debye-Scherrer’s formula. The peaks corresponding to the impurity were not found in the XRD pattern, confirming the high purity of the synthesized ZnO nanoparticles. UV-Visible absorption spectra confirmed a strong absorption maximum below 400 nm.
