| 英文摘要 | Simplified phosphorescent light-emitting devices with the structure ITO/MoO3 (3 nm)/4,4'-bis(9H-carbazol- 9-yl)biphenyl (CBP): x wt% tris(2-phenylpyridine)iridium(III) [Ir(ppy)(3)] (30 nm)/3-(biphenyl-4-yl)4-phenyl-5-(4-tert-butylphenyl)-4H-1,2,4-triazole (50 nm)/LiF (1 nm)/Al (100 nm) are demonstrated. The optimized organic light-emitting diode with CBP: 25 wt% Ir(ppy)(3) as a light-emitting layer showed a peak current efficiency of 46.8 cd A(-1), which is 1.64 times that of the reference device with the structure ITO/ N,N''-bis(naphthalen-1-yl)-N,N'-bis(phenyl)benzidine (30 nm)/CBP: 8 wt% Ir(ppy)(3) (30 nm)/2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline (10 nm)/(4,7-diphenyl-1,10-phenanthroline) (40 nm)/LiF (1 nm)/Al (100 nm). The improvement in efficiency is attributed to the charge-trapping effect of the heavy doping of Ir(ppy)(3) and the excellent hole-transporting ability of the CBP layer doped with Ir(ppy)(3). When we incorporated bis(4,6-difluorophenyl-pyridine)(picolinate)iridium(III) into the CBP: 25 wt% Ir(ppy)(3) layer, the device showed a higher efficiency of 71.2 cd A(-1), which is superior to that of previously reported simplified organic light-emitting diodes. |
