摘要

We report a feasible method to realize tunable surface plasmon-polariton (SPP) resonance in organic light-emitting devices (OLEDs) by employing corrugated Ag-Al alloy electrodes.The excited SPP resonance induced by the periodic corrugations can be precisely tuned based on the composition ratios of the Ag-Al alloy electrodes.With an appropriate composition ratio of the corrugated alloy electrode,the photons trapped in SPP modes are recovered and extracted ef-fectively.The 25％ increasement in luminance and 21％ enhancement in current efficiency have been achieved by using the corrugated Ag-Al alloy electrodes in OLEDs.
