nm, respectively. The structure and the morphology of deposited films were evaluated by x-ray diffraction (XRD) and scanning electron microscopy (SEM). The average grain size of TiO2 nanocrystals was in the range of 25-30 nm in the annealed fabricated thin films. The microstructure of annealed films was anatase. The transmittance of the films was measured using ultraviolet–visible light ( UV–vis) pectrophotometer.Photocatalytic activity of the samples was evaluated by the degradation of Methylene Blue (MB) dye.
