Abstract

Un-doped and indium (0'-9 at.%) doped ZnO nanoparticles were prepared by the sol-gel method. The nanoparticles were heated at 700 °C'-BOo for 1 hour in air and then analyzed by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray (EDS), Raman spectra and photoluminescence (PL). The results were compared to investigate the structural characteristics and physical properties. XRD patterns of the Indium-doped ZnO (IZO) nanoparticles were similar to those of the ZnO nanoparticles. Notably, the crystalline quality of the ZnO nanopartides had reduced with increasing the concentration of indium doping. The In2O 3 phase of IZO and the crystallized structures affected the UV emission band and the green emission band of PL. The Indium-doped (5 at.%7at.%) ZnO nanoparticles possessed higher crystalline quality and better optical properties.
