摘　　要：基于ITO/MoO_3/NPB/TCTA/FIrpic∶TCTA/FIrpic∶X/Y/LiF/Al结构,研究了主体材料的能级和三线态激子,以及电子传输材料的能级对器件性能的影响。研究发现,X与Y分别为TmPyPb与TPBI的双发光层蓝光器件的性能最优,最大发光效率达到了23.78 cd/A。研究表明,电子主体材料可以调节激子分布,影响能量转移。The effects of the host materials and electron transport materials on the blue organic light-emitting diodes was studied by researching the effects of energy level and triplet exciton on the performance of devices based on the structure of ITO/MoO 3/NPB/TCTA/FIrpic ∶TCTA/FIrpic ∶ X/Y /LiF/Al. The high quality double emission layers device with the peak efficiency of 23.78 cd/A was obtained when X and Y are TmPyPb and TPBI. The results showed that the distribution of exciton and energy transfer can be adjusted and influenced by host materials and electron transport materials.
