1. An organic electroluminescent device comprising:
a substrate;
a first electrode disposed over the substrate;
an organic emissive layer, comprising an organic emissive material, disposed over the substrate;
an enhancement layer comprising a plasmonic material exhibiting surface plasmon resonance that non-radiatively couples to the organic emissive material and transfers excited state energy from the organic emissive material to non-radiative modes of surface plasmon polaritons; and
an outcoupling layer disposed over the enhancement layer that converts at least 20% of energy in the non-radiative modes of the enhancement layer to photons in free space.
