The oxidation process was applied to CuO films in three different mediums as air, oxygen and argon. CuO films were kept at 400 °C for 2 hours in each medium during the oxidation process. The effect of the selected medium in the oxidation process on the physical properties of the CuO films was investigated. This study showed that the physical properties of the CuO films can vary significantly in different oxidation mediums. XRD studies reveal that all the films are polycrystalline with monoclinic structure and exhibit (-111) and (111) preferential orientations. Grain sizes were determined to vary in the range of 26-28 nm in different oxidation mediums. The XRD results were confirmed by Raman spectrum analysis. The band gap values increased between from 1.80 to 2.11 eV. In addition, it was discovered that with the oxidation of CuO films in argon medium, crystalline melanothallite structure was formed and the surface morphology was significantly changed.}, number={32}, publisher={Osman SAĞDIÇ}, organization={Çankırı Karatekin Üniversitesi}
