Effect of oxidation time on structural, optical and electrical properties of mixed copper oxides nanocrystallites
Mixed nanocrystalline copper oxides were prepared from pre-sputtered copper films at 500 °C for various oxidation times. Mixed orthorhombic Cu64O and monoclinic CuO phases with CuO phase ration varied from 57.8 to 90.8% were obtained upon varying the oxidation time from 1 to 3 h. SEM observations revealed the nanocrystallites morphologies for the oxidized films. The film oxidized for 1 ... Read more
