Abstract: An OLED is disclosed that includes an enhancement layer having optically active metamaterials, or hyperbolic metamaterials, which transfer radiative energy from the organic emissive material to a non-radiative mode, wherein the enhancement layer is disposed over the organic emissive layer opposite from the first electrode, and is positioned no more than a threshold distance away from the organic emissive layer, wherein the organic emissive material has a total non-radiative decay rate constant and a total radiative decay rate constant due to the presence of the enhancement layer, and the threshold distance is where the total non-radiative decay rate constant is equal to the total radiative decay rate constant; and an outcoupling layer disposed over the enhancement layer, wherein the outcoupling layer scatters radiative energy from the enhancement layer to free space.

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.
