Abstract Polymer light-emitting diodes (PLEDs) have recently demonstrated the potential for multiple commercial products. However, to realize this potential, several drawbacks of existing designs of PLEDs should be properly addressed, including insufficient luminous efficacy. In this study, a feasible solution to this problem is presented along with the design and fabrication of a novel platinum/nickelous oxide (Pt/NiOx) anode for PLED. The proposed design allows to achieve 40% increase in average current efficiency, four-times increase in the electroluminescence intensity compared to currently available PLEDs, and significantly reduce anode thickness. These results demonstrate that Pt/NiOx can become the mainstream anode material for high-performance PLEDs.
