The feasibility of using Cu as reflective anode for constructing efficient top-emitting organic light-emitting diode (TOLED) has been demonstrated. The MoOx modification can considerably enhance the work function of Cu anode, which contributes to the improvement of hole injection and thereby promoting device efficiency. In comparison with the TOLED having conventional Ag anode, the device having Cu anode shows inferior efficiency partially resulted from low reflectance of Cu, but the TOLED with Cu anode takes many advantages such as low-cost fabrication, enhanced pixel contrast ratio, weak microcavity effect and reduced leakage current. These improved performances are of great importance for practical applications, suggesting that Cu provides an alternative approach for realizing TOLED-based applications.
