| Abstract | ZnO/SnO2 thin films with different percentage (1:1,1:2,2:1) were deposited on a glass substrate by Spray Pyrolysis technique using solution of zinc acetate ,tin chloride and air as the carrier gas at 400 °C temperature. The structural properties of the composite films are investigated by x-ray diffraction andAFM. The optical spectra of the films were measured in the wavelength range of 300 –1100nm by UV-VIS Spectrometer device.Optical constants such as Absorption coefficient α, refractive index n , extinction coefficient k and dielectric constant were determined from transmittance spectrum in the UV-VIS regions. The films were found to exhibit high transmittance inthe visible regions. The energy band gapof the films were evaluated as 3.85,3.70,3.70,3.85 and 3.60 eV for ZnO pure,SnO2 pure and the percentage (1:1,1:2,2:1) of ZnO:SnO2 respectively. |
