Abstract

Pure and metals (Mn & Mg) doped zinc oxide (ZnO, ZnO/Mn and ZnO/Mg) thin films have been successfully grown onto a glass substrates by low cost SILAR method. The structural, morphological, compositional, functional group and optical properties of the prepared films were studied using X-ray diffraction, scanning electron microscope and EDAX, FTIR and UV-visible spectrophotometer, respectively. The structure of the films were found to be hexagonal with polycrystalline in nature with preferential orientation along (002) plane. From Fourier Transform Infrared spectroscopy, the presence of functional groups and its corresponding molecular vibrations were assessed. In UV-visible spectroscopy, the obtained direct optical band gap values 3.46, 3.56 and 3.7 eV for pure, Mn and Mg doped ZnO thin films, respectively. Morphological results showed that the remarkable changes in morphology due to the effect of metal doping. EDAX studies showed that the presence of zinc and oxygen content and also a doping metal ions.
