Abstract
Thin-films (ZnO)(0.4)(CdO)(0.6) composites were grown by the spray pyrolysis technique on glass substrates heated to a temperature of 350°C. The structural properties have been identified using X-ray diffraction spectra. The deposited films are of polycrystalline natures. Both the two materials mixed (ZnO and CdO) were well observed in the X-ray diffraction plot. The optical properties were also studied using UV- Vis optical spectroscopy. transmittance and reflectance are measured in the wavelength range of 200nm to 2500nm. The evaluation of the optical gap shows that this composite has two gaps, the first concerns the ZnO and the second concerns the CdO.
