Structural, optical and morphological studies of SILAR grown ZnO thin film and double coated CBD grown ZnO thin film

Abstract

Abstract The Zinc oxide thin films were produced on glass substrate by using SILAR and CBD methods. The structural, optical and morphological properties of the films were investigated by X- Ray diffractometer, UV-visible spectrometer and scanning electron microscopy respectively. The XRD pattern shows that in both the samples preferential growth orientation is along (0 0 2) plane. The optical band gap was found to be 3.31eV for SILAR ample and 3.18eV for CBD grown sample. The morphology analysis shows that the particle size in SILAR grown sample was high. A vertically aligned nanorods were obtained in CBD grown sample.
