Mg-doped ZnO Films by Sol-Gel Spin Coating Method

Derya G. Peker, Sinan Temel, Murat Nebi


Undoped and Mg doped ZnO films were deposited on glass substrate by sol-gel spin coating method. This method is a simple, economic and effective method to produce high quality films. Structural, morphological and optical properties of films were investigated by using X-Ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM) and UV-Visible Spectroscopy respectively. The structure, surface morphology, optical transmittance and band gap were found to depend on the Mg content of the film. XRD results showed that the films were polycrystalline nature and FESEM images proved that the films were homogenous and compact. It was observed that the band gap increases with Mg doping.
