Abstract: 

In the present work we prepared conducting and transparent thin films ZnO:SnO2 by pyrolysis spray technique on glass substrates. These films are obtained starting from solution of zinc acetate and tin acetate dissolved in methanol, at substrate temperature T = 350 °C. Our interest is on the investigation of percentage of phase on the optical and structural properties of these films. For that we used the optical spectroscopy of transmission UV-Visible for the optical characterizations and the diffraction of X-ray for the structural characterizations of our films. UV-Visible spectrophotometer confirms that it is possible to obtain good transparent films with a transmittance from 65 to 85% in the visible. The increase in Sn increases the optical band gap. This last varies from 3. 3to 3.77 eV. The structural analysis showed that the films (ZnO and Zn0.5Sn0.5O) deposited have a preferential orientation according to the direction (002), this result confirms that the majority phase is of ZnO.
