摘要/Abstract

摘要：

使用真空蒸镀法分别制作了以TCTA和CBP做为主体材料的绿色磷光OLED器件,发现采用CBP为主体材料的器件比采用TCTA为主体材料的器件更稳定。之后在采用CBP作为主体材料的器件中分别掺杂了3%,6%,9%的蓝色客体磷光材料FIrpic,得出在掺杂浓度为3%时,即器件结构为ITO/HAT-CNTAPC/CBP:8%Ir (ppy)3:3%FIrpic/Tmpypb/Liq/Al时性能最佳。FIrpic掺杂比例为3%时得到最大功率效率和最大电流效率分别为54.3 lm/W和64.8 cd/A,最大亮度为51 940 cd/m2。研究表明Firpic的掺杂,在不改变绿色磷光OLED光谱性能的同时,有助于提高绿色磷光OLED的电光性能。

Abstract:

Green phosphoresent OLEDs have been fabricated by vacuum evaporation with the structure based on TCTA and CBP as the host.We find that it is more stable using CBP as host than TCTA.Then the blue phosphoresent material Firpic is doped into the emitting layer of OLED devices based on CBP with the concentration of 3%,6%,9% respectively.The best performance is found in the structure ITO/HAT-CNTAPC/CBP:8%Ir (ppy)3:3%FIrpic/Tmpypb/Liq/Al.The maximum power efficiency and current efficiency values are 54.3 lm/W and 64.8 cd/A for 3% FIrpic doping respectively,with a maximum luminance of 51 940 cd/m2.Research shows that doping FIrpic into green phosphorescent OLED improves the device's electro-optic performance without affecting the spectrum of the device.
