Researchers from Jilin Univeristy in Changchun, China, have managed to improve the brightness of OLED devices by 25% (21 enhancement in current efficiency) by applying corrugated alloy (Ag-Al) electrodes.

The researchers say that the periodic corrugations were precisely tuned based on the composition ratio of the alloy to efficiently recover the photons trapped in surface plasmon-polariton resonance.
