摘要： The present invention relates to efficient organic light emitting devices (OLEDs). More specifically, the present invention relates to white-emitting OLEDs, or WOLEDs. The devices of the present invention employ two emitters in a single emissive region to sufficiently cover the visible spectrum. White emission is achieved from two emitters in a single emissive region through the formation of an aggregate by one of the emissive centers. This allows the construction of simple, bright and efficient WOLEDs that exhibit a high color rendering index.

摘要： Charge transport enhancement layers and structures are provided that may improve the performance of organic devices, specifically organic light emitting devices. A charge transport enhancement layer may include a layer or an inorganic material, metal oxide, halide, and/or alkali disposed between two organic layers, and separated from the cathode by an intervening organic layer. One or more CTELs may be used, such as in an alternating stack of organic and CTEL layers. Surprisingly, it has been found that the use of one or more CTELs arranged in a stack with intervening organic layers may improve the performance of the device even where the layer is not directly adjacent to the cathode.

摘要： An organic light emitting device is provided having an emissive layer with an internal interface. The concentration of a second phosphorescent material in a second organic layer is different from the concentration of a first phosphorescent material in a first organic layer, creating the interface. The materials in the first and second organic layers may be the same or different. In addition to this interface within the emissive layer, the device has one or more features designed to mitigate failure mechanisms which may be associated with electrons or excitons passing from the cathode through the emissive layer to damage organic layers on the anode side of the emissive layer. In addition, devices are provided having an interface within the emissive layer as described above, and a lower energy emissive material on at least one side of the interface.
