Abstract

Nanocrystalline ZnO thin films are deposited on glass substrates by by sol gel process. The crystalline structure, morphology and size were determined by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The X-ray diffraction results indicated that ZnO nanoparticles have a hexagonal wurtzite structure and average particle size is about 4 nm. Photoluminescence spectra showed two peaks which were in the UV emission centered at 375 nm, and visible emission centered at 475 nm.
