| 摘 要： | 在PVK/BCP双层电致发光器件中发现了电致激基复合物的发光，器件的光谱中，除了有与光致发光相同的发光峰，在长波方向还有一个新的发光峰，该发光峰就是电致激基复合物的发光，发光来源于BCP的激发态向PVK基态的跃迁。PVK∶BCP混合型器件由于复合区域扩展，BCP分子可以与PVK充分接触，因此电致激基复合物的发光更强。不论是在双层器件还是在混合型器件中，随驱动电压的增加，电致激基复合物的发光都会增强，而混合型器件更加明显，当电压比较高时，器件只有电致激基复合物的发光了，而没有本征发光。

| Abstract: | Electroplex emission based on poly(N-vinylcarbazole) (PVK) and 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline (BCP) has been studied. A emission peak at 595 nm was observed in EL spectrum but not in PL spectra in the devices. The emission originates from the transition between the excited state of BCP and the ground state of PVK. Because of the increase of emission zone, the device of PVK: BCP blend exhibited stronger electroplex emission. The emission of electronplex was enhanced for both of PVK/BCP double layer device and PVK:BCP blend device, and it is stronger for blend devices. At higher drive voltage, only electroplex emission was observed in the blend device. |
