Optoelectronics properties of TiO2Cu thin films obtained by sol gel method

Abstract : In this research, Cu-doped TiO2 thin films have been successfully deposited onto a glass substrate by Sol–gel technique using dip coating method. The films were annealed at different annealing temperatures (400–500 °C) for 1 h. The structural, optical and electrical properties of the films were investigated and compared using X-ray Diffraction, UV–visible spectrophotometer and 4-point probe method. Optical analysis by mean transmittance T(λ) and absorption A(λ) measurements in the wavelength range between 300 to 800 nm allow us to determine the indirect band gap energy. DRX analysis of our thin films of TiO2Cu shows that the intensities of the line characteristic of anatase phase increasing in function of the temperature. © 2017, Springer Science+Business Media, LLC.
