钙铝镁合金阴极对WOLED器件性能的影响
Effects of Ca/Al/Mg Alloy as Cathode on The Performance of White Organic Light-emitting Devices
摘要
Abstract
Based on the red and green/blue light emitting layer, six white phosphorescent OLEDs are fabricated by using Ca/Al/Mg alloy as cathode, and the effects of different proportion of Ca/Al/Mg alloy on OLEDs are researched by changing the doping ratio of Mg. The device structures are as follows:ITO/MoO3 (30 nm)/NPB(40 nm)/mCP∶Firpic(8%)(40 nm)/CBP∶R-4B(2%)∶Ir(ppy)3(14%)(5 nm)/TPBi(10 nm)/Alq3(40 nm)/Ca∶Al∶Mg(x%) (100 nm)(x=0, 5, 10, 15, 20, 25). The experiment results show that the cathode with Mg mass fraction of 15%has good electron injection characteristics which can effectively improve the light-emitting characteristics of the de-vice. The maximum brightness is 1 504 cd/m2 , the maximum current efficiency is 14. 3 cd/A, and the color coordi-nates is close to (0. 46, 0. 42).关键词
