    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.
