Abstract
ZnO thin films were deposited on glass substrates by sol-gel dip coating method under different baking temperatures of 80, 100, 150, 200, and 250 °C. The influence of baking temperature on structural, morphological, and optical properties of ZnO transparent thin films were investigated by X-ray diffraction, Scanning Electron Microscope, and UVVisible spectroscopy. X-Ray Diffraction results show crystal structure of ZnO wurtzite structure. The optical transmittance spectra of ZnO thin films shows high optical transmittance in visible range. At high baking temperature condition, the XRD peak intensities of the deposited thin films were higher than the low baking temperature condition. The results imply that baking temperature has significant influence on both structural and optical properties of sol-gel derived ZnO thin films.
