基于PVK:TPD/Bphen界面激基复合物和电致激基复合物发射的WOLED
White organic light-emitting diode based on exciplex and electroplex emission at PVK:TPD/Bphen interface
利用真空蒸镀制备了白光有机电致发光器件ITO/PVK(聚乙烯咔唑):TPD(N,N'-二苯基- N,N'-二(3-甲苯基)联苯胺)/Bphen(4,7二苯基-1,10-邻菲罗啉)/LiF/Al。器件的电致发光光谱上有位于401nm,421nm,480nm,600nm附近的四个发光峰。401nm,421nm附近的发光峰来自于TPD分子的发射。位于480nm附近的发光峰来自于PVK:TPD/Bphen 界面TPD与Bphen分子间激基复合物的发光，位于600nm附近的发光峰来自于PVK:TPD/Bphen 界面PVK和Bphen分子间的电致激基复合物发光。研究分析了激基复合物发射和电致激基复合物发射在同一个界面时的动态过程。
In this paper, white organic light-emitting diode (WOLED) with a structure of ITO/poly(N-vinylcarbazole) (PVK) : N,N'-diphenyl-N,N'-bis(3-methylphenyl)-1,1'-biphenyl-4,4'-diamine (TPD)/ 4,7-Diphenyl-1,10-phenanthroline (Bphen) / LiF/Al has been fabricated via thermal evaporation technique.There are four emission peaks at about 404nm, 421nm, 476nm,600nm in EL spectra of this device. The emission peak at 401nm and 421nm come from TPD molecular emission. The emission peak at 480nm is from exciplex emission between TPD molecular and Bphen molecular, and the emission peak at 600nm comes from electroplex emission between PVK molecular and Bphen molecular at the PVK:TPD/Bphen interface. The dynamic process has been investigated when exciplex emission and electroplex emission are in the same organic interface.
