Structural and Optical Characterization of ZnO Nanoparticles Synthesized Via Low Temperature Precipitation Method

Abstract

ZnO nanoparticles were successfully synthesized via a low temperature and simple precipitation method. Crystallinity, phase purity and structural properties of as prepared material were analyzed by X-ray diffraction pattern (XRD), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM) and Atomic Force Microscopy (AFM) with 32 nm average crystallite size. Additionally, the optical properties of the sample were investigated by using Uv-Vis-NIR and Photoluminescence spectroscopy with an energy band gap at 3.09 eV. These results should be useful in developing optoelectronic devices such as UV-LEDs and laser diodes.
