| Abstract | ||
| The effect of the annealing on the optical transmission , absorption coefficient, dielectric constants (εr),( εi) ,Skin depth and the optical energy gap of (ZnO)x(CdO)1-x thin films with (x=0.05) deposited on preheated glass substrates at a temperature of (450 C°) by chemical pyrolysis technique were performed . These films show direct allowed inter band transition that influenced by annealing at ( 450 C°) for two hours . And it also found that the optical energy gap has been increased from about (2.50 eV) before annealing to about (2.65 eV) after annealing , from the analysis of the absorption and transmission spectra in the wavelength range (380-900nm) . The results show that all these parameters were affected by annealing. | ||
