Abstract. Copper-zinc ferrite (CuFe 2 O 4 ) films have been deposited successfully by spray pyrolysis technique. Ferrite films deposited of thickness (450 ± 15nm) at temperature (400 ± 10 o C) and annealing (600 o C) for range of (4h). The compound was doping with zinc at rates (x= 0,0.2,0.4). The crystalline structure of the prepared films was determined Tetragonal a spin Ferrite in peak (211), and when it was doping with zinc, it turned into cubic in peaks (311). The particle size was found to decrease by increasing the concentration of (Zn). The optical properties have been identified of films wavelengths of (300-900) nm, The results showed that the transmittance for all thin films increases as the wavelength increases then saturates at higher wavelengths .
