Abstract

Blue fluorescent material combined with red uorescent dye doped into tris-(8-hydroxyquinoline) aluminum (Alq) in multilayer organic light-emitting diodes(OLEDs) were investigated. Basis device architecture is indium tin oxide (ITO)/ N,N -bis-(1-naphthyl)-N,N -diphenyl-1,1 -biph-enyl-4,4 -diamine(NPB 20nm)/ 4, 4'-bis (2,2'-diphenyl vinyl)-1,1'-biphenyl (DPVBi 10nm / tris-(8-hydroxyquinoline) aluminum (Alq) 5H-benzo[ij] quinolizin-9-yl)ethenyl] -4H-pyran-4-ylidene]propane-dinitrile (DCM2 0.8% 7nm / (Alq 13nm)/LiF 0.65nm /Al. Exciton recombination zone is located at DPVBi and DCM2 doped into Alq layers. The Commission Internationale de1'Eclairage (CIE) coordinates of the device change from (0.4458,0.4589) at 5V to (0.3379,0.2611) at 12V that are well in the white region. Its maximum luminance was 4248 cd/m2 at 12V, and maximum current ef ciency was 7.21cd/A at 5V, respectively.
