| Abstract | ||
| Nanostructured ZnO thin films have been synthesized by Sol Gel process. The ZnO precursors were prepared by using zinc acetate dehydrate and a mixed solution of monoethanolamine and ethanol, and were prepared with Zn2+ concentration 0.5mole. The films were deposited on glass substrates by spin coating at 3000 rpm for 30s at room temperature. These films were postheated at 400oC for 1h at air. ZnO thin films have a polycrystalline and wurtzite structure. The crystallite size was determined by X-ray diffraction using Scherrer method. The crystallite size of ZnO thin film was 23.4nm. The transmittance spectra of ZnO films were 85% in the visible region from 600 to 800nm. The energy band gap is found to be 3.24 eV for ZnO film. | ||
