Structural and Optical Properties for TiO2 thin films Prepared by Screen Printing method

Abstract

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
