Abstract
TiO2 and TiO2:Cu films were deposited by spray pyrolysis (SP). X-ray diffraction reveals that deposited films have a polycrystalline structural. The AFM image of the surface reveals that roughness and root mean square affected by doping. Optical transmission of films was found to decrease from 94 % to 84 % with the as the doping percentage increase to 3. Optical bandgap (Eg) of TiO2 thin film was 3.947eV. The bandgap is shifted to lower energies upon doping.
