Abstract
An organic light-emitting diode (OLED) device, comprising: first and second transparent electrodes, and one or more layers of organic material formed between the first and second transparent electrodes, the layers of organic material including one or more light-emitting layers; a reflective layer having a surface plasmon-polariton-supporting reflective surface located on a side of either of the first or second transparent electrodes opposite to the organic material layers; and a scattering layer in optical contact with the organic material layers and the electrodes. In certain embodiments, layer spacing is preferably designed such that the distance between the reflective surface and at least one of the one or more light-emitting layers is equal to or greater than 60 nm. Additionally, a low-index layer is preferably employed in various embodiments to improve device sharpness.
