摘要: | We demonstrate a highly efficient white organic light emitting device with fluorescent small molecule 4,4'-bis(9-(1-naphthyl)anthracene-10-yl)biphenyl (BUBH-3). With a simple device architecture of indium tin oxide/tris 4,4',4'-tris-N-naphthyl-N-phenylamino-triphenylamine (60 nm)/N,N'-bis-(1-naphthyl)-N,N'-diphenyl-1,1'-biphenyl-4,4'-diamine (10 nm)/BUBH-3 (45 nm)/Alq(3) (15 nm)/LiF (1 nm)/Al (150 nm), a white light with CIEx,y color of (0.31,0.36) was generated. The device achieved one of the best single-emitting-material electroluminescence performance of white organic light-emitting devices with efficiencies of 7.0 cd/A and 3.17 lm/W at 6.9 V.
