Studying the Optical Properties of (Zn1-xFexO) Thin Films prepared by Chemical Spray Pyrolysis technique


(Zn1-xFexO) (x = 0, 0.2, 0.4, 0.6 and 0.8) thin films were prepared by Chemical Spray Pyrolysis technique, on glass substrates at a temperature of (400 °C), The optical properties were studied by recording the absorption and transmission spectra in the range (350-900) nm, the optical constants such as (absorption coefficient, extinction coefficient and optical conductivity) were calculated for the films as a function of photon energy, we found that the transmittance and the optical band gap for the direct allowed electronic transition decrease with the increasing of (Fe) concentration.
