电子主体材料对蓝光OLED的影响
Effects of Host and Electron Transport Materials on Blue Organic Light-emitting Diodes
摘要
基于ITO/MoO3/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。
Abstract
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/MoO3/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.
