我们展示了高效的单层聚合物磷光发光器件的基础上发绿光的铱配合物和聚合物主体共掺杂的电子传输和空穴传输分子。这些器件可以在相对较低的电压下工作，在发光效率超过30 cd/A时，功率转换效率高达24 lm/W。这些设备的整体性能表明，有效的电致磷光器件与可接受的工作电压可以实现在非常简单的设备结构制造的旋涂。
We demonstrate efficient single-layer polymer phosphorescent light-emitting devices based on a green-emitting iridium complex and a polymer host co-doped with electron-transporting and hole-transporting molecules. These devices can be operated at relatively low voltages, resulting in a power conversion efficiency of up to 24 lm/W at luminous efficiencies exceeding 30 cd/A. The overall performances of these devices suggest that efficient electrophosphorescent devices with acceptable operating voltages can be achieved in very simple device structures fabricated by spin coating.
