Abstract
A method for improving the operation of an OLED includes maximizing on-radiative transfer of excited state energy from the OLED's organic emissive material to surface plasmon polaritons in an enhancement layer by providing the enhancement layer no more than a threshold distance away from the organic emissive layer; and emitting light into free space from the enhancement layer by scattering the energy from the surface plasmon polaritons through an outcoupling layer that is provided proximate to the enhancement layer but opposite from the organic emissive layer.
