      Copper sulphide films prepared by reactive evaporation, when heated in air at 500 K, oxidized to Cu2O after a series of intermediate chemical transitions. Golden yellow coloured Cu2O films showed a large absorption before the fundamental absorption edge. The optical band gap was found to be (2.29±0.02)eV. When these Cu2O films were further heated they got converted to CuO and the optical band gap was found to be (2.17±0.02)eV.
