Abstract
Devices and techniques are provided for achieving OLED devices that include one or more enhancement layers formed at least partially from a plasmonic material exhibiting surface plasmon resonance that non-radiatively couples to an organic emissive material in the organic emissive layer, where a majority of excited state energy is transferred from the organic emissive material to a non-radiative mode of surface plasmon polaritons of the enhancement layer.
