摘要	Improved efficiency and colour purity of blue electrophosphorescent devices based on bis[(4,6-difluorophenyl)-pyridinato-N,C(2)](picolinato)Ir(III) (FIrpic) were demonstrated by codoping a fluorescent emitter 2,5,8,11-tetra-t-butyl-perylene (TBPe). The optimized device codoped with 8 wt% FIrpic and 0.15 wt% TBPe shows a maximum current efficiency and power efficiency of 11.6 cd A(-1) and 7.3 lm W(-1), which were increased by 20% and 40%, respectively, compared with that of the reference device. Also, a blue shifted electroluminescent spectrum of the codoped devices was observed with doping concentration of TBPe, leading to improved colour purity of the devices. The improved efficiency and colour purity of the codoped devices were attributed to the simultaneous emission of the two emitters.
