摘要 | Evidently enhanced electrophosphorescence of [Cu(bis[2-(diphenylphosphino)phenyl] ether)(6,7-dicyanodipyrido [2,2-d:2('),3(')-f] quinoxaline)] BF4 (Cu-I complex) by codoping bis[(4,6-difluorophenyl)-pyridinato-N, C-2](picolinato)Ir(III) (FIrpic) into the same host, 4,4(')-N,N-'-dicarbazole-biphenyl, was demonstrated. The device codoped with 8 wt % FIrpic and 2 wt % Cu-I complex shows a maximum current efficiency and power efficiency of 26.6 cd/A and 17.8 lm/W, respectively, which were increased by factors of 2.6 and 2.1 compared with the 2 wt % Cu-I complex monodoped device. The improvements of the devices were testified to the efficient energy transfer from FIrpic to the Cu-I complex. The detail of the energy transfer mechanism between the two phosphors was also proposed. (c) 2007 American Institute of Physics. |
