摘要： Described is a light emitting diode (LED) that uses hybrid nanostructures to enhance light emission intensity and light extraction efficiency. In at least one embodiment, nanostructures comprise a combination of metal and metal oxide layers that simultaneously provide optical property for emission enhancement and support electrical property for charge transport to support electroluminescence. In at least one embodiment, LED comprises multiple layers including a hybrid metal-metal oxide layer, light-emissive layer, and a light outcoupling layer. In at least one embodiment, metal-metal oxide layer can be formed by evaporation or sputtering. In at least one embodiment, light-emissive layer can be formed by emissive layer spin coating. In at least one embodiment, light outcoupling layer is formed by imprinting or by particle lithography.
