Abstract |
|
|
| Titanium dioxide (TiO2) thin films have been deposited on microscopic glass substrate by spray pyrolysis technique.
The effect of deposition parameters such as substrate temperature, molarity (precursor concentration) and solution spray rate on the
structural, surface morphological and optical properties of the films have been studied. The prepared films were characterized by X-ray
diffraction (XRD), scanning electron microscope (SEM) with EDS and UV-Vis spectroscopy. The XRD patterns indicated that the films
have amorphous and polycrystalline structure and the size of the crystallites have been changed from 9 to 48 nm. The optical band gap
of the TiO2 films is determined to be about 3.40 to 3.65 eV to the change of deposition conditions. |
