Abstract :
Polycrystalline Cu_2O thin films were obtained on glass substrates using by silar method at 70 °C. XRD analysis showed the films are a cubic structure and lattice parameters were calculated. The surface morphology of the films were imaged by FE-SEM (Field Emission Scanning Electron Microscope). In order to determine the optical properties of the Cu_2O thin films UV/vis spectrophotometer was used. Optical transmittance (T %) values of the Cu_2O films were determined in the wavelength range 300-1100 nm at room temperature. Semiconductor Cu_2O of the thin films optical transmittance values were found to be 50-70% in the visible region. Energy band gap values (Eg) of the films were found to be 2.53-2.62 eV.
