    摘要: An organic light emitting device comprising, an anode, a cathode, and an emissive layer, located between the anode and the cathode, of a host compound, a first compound capable of phosphorescent emission at room temperature, and a second compound capable of phosphorescent emission at room temperature is provided. At least 95 percent of emission from the device is produced from the second compound when an appropriate voltage is applied across the anode and cathode.

    摘要: An organic light emitting device is provided. The device includes an anode and a cathode. A first organic layer is disposed between the anode and the cathode. The first organic layer is an emissive layer that includes a first organic emitting material. The device also includes a second organic layer disposed between the anode and the first organic layer. The second organic layer is a non-emissive layer. The second organic layer includes an organic small molecule hole transport material having a concentration of 50 to 99 wt %, and an organic small molecule electron transport material having a concentration of 0.1 to 5 wt %. Other materials may be present.
