摘要	Low-voltage and high-efficiency nondoped phosphorescent organic light-emitting devices are fabricated by introducing a simple triplet double-quantum-well structure with an Ir(III) complex as potential well layer (PWL) and emitting layer (EML). The effects of various potential barrier layer (PBL) on device performances are discussed. Remarkably, the device with 1,3,5-tris(N-phenyl-benzimidazol-2-yl) benzene (TPBi) as PBL shows a low turn-on voltage of 2.30 V, a maximum power efficiency of 30.5 lm/W at 2.65 V and 24.5 lm/W with 1000 cd/m(2) at 3.75 V. We attribute these to the efficient carrier/exciton confinement function of TPBi and the improvement of carrier injection/balance in PWL/EML by self-balancing effect.
