The properties of copper-doped indium tin oxide (ITO:Cu) films deposited by rf-magnetron sputtering, and organic light-emitting devices (OLEDs) using an ITO:Cu film as an anode were investigated. The resisitivity of the ITO:Cu films increased with Cu doping. The work function of each ITO:Cu film was higher than that of an ITO film. The structure of the ITO:Cu films was an In2O3-type structure when the mixing rate of CuO in the film was up to 5 vol %, and the structure was amorphous in more strongly copper-doped films. The properties of the OLEDs were varied by the mixing rate of copper in the ITO:Cu electrodes. Each OLED using the ITO:Cu electrode exhibited higher luminance than the conventional OLED at the same current density. The OLED using the ITO:Cu electrode containing 5 vol % CuO exhibited a longer lifetime than the conventional OLED. However, further copper doping into the ITO:Cu electrode affected the long-term stability of the OLEDs.
