Surface plasmon polariton modification in top-emitting organic light-emitting diodes for enhanced light outcoupling [PDF]

, 2014
We report on the enhanced light outcoupling efficiency of monochrome top-emitting organic light-emitting diodes (OLEDs). These OLEDs incorporate a hole transport layer (HTL) material with a substantially lower refractive index (∼ 1:5) than the emitter ...
