Nitrogen doped TiO2 thin film was deposited by a DC reactive magnetron sputtering on glass and SiO substrate and then annealed at 400° C. Deposition was performed at Ar + O2+N2 gas mixture with a pressure of 1.0 Pa and oxygen and nitrogen with a constant pressure of 0.2 Pa and 0.1 Pa, respectively. The pure TiO2 thin film was deposited at Ar+O2 gas mixture with a pressure of 1.0 Pa and oxygen with a constant pressure of 0.2 Pa. ZnO thin layer was used as a buffer layer. The thicknesses of layers TiO2–x)Nx \TiO2\ZnO were approximately 200nm, 800nm, and 80
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.<\div>
