In this study, Structural and Optical Properties of titanium dioxide thin films are studied, TiO2 (Anatase) thin films were prepared by screen printing (SP) method. X-ray diffraction analysis showed that the structure of TiO2 films are polycrystalline and the lattice system is tetragonal. The main diffraction peak of TiO2 was (101) at 2θ=25ᵒ. The data of optical absorption indicated that TiO2 thin films prepared by SP have a direct optical band gap (about 3.1eV). The data of reflectivity was also used to calculate the band gap and was around 2.95 eV http://dx.doi.org/10.25130/tjps.24.2019.093
