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. |
