Abstract
Pure and Mg-doped ZnO thin films have been fabricated by a sol-gel spin coating method. The as prepared films were annealed at 400 °C. The structural, optical, morphological and luminescent characteristics were studied by using X-ray diffraction (XRD), diffuse reflectance (DR), scanning electron microscopy and photoluminescence spectroscopy techniques. XRD results show the polycrystalline behavior of deposited films without any impurity or formation of extra phase. DR spectra exhibit the blue shift in the absorption edge gap after Mg doping. It has been observed that the band-gap of the fabricated films rises with the increase in the Mg doping. The obtained results have been explained by existing literature and a good comparative study has been made.
