High color rendering white organic light-emitting diodes fabricated using a broad-bandwidth red phosphorescent emitter |
| 초록 |
High color rendering white organic light-emitting devices (WOLEDs) were developed using a broad-bandwidth red phosphorescent iridium complex, bis[2-(1-naphthyl)benzothiazolato-N,C2′]iridium(III) acetylacetonate [Ir(absn)2(acac)]. The red phosphorescent emitter Ir(absn)2(acac) was used to fabricate blue-red and blue-green-red WOLEDs by combining blue-emitting FIrpic and green-emitting Ir(chpy)3 in multiple-emissive layers. Mixed host emissive layers were employed using host TCTA and DCzPPy. The effects of the emissive layer thickness and the doping ratios of different color dopants on WOLED performances were investigated. The WOLED based on ITO/TAPC/TCTA:FIrpic (10%):Ir(absn)2(acac) (4%)/TCTA:Ir(chpy)3 (9%, 6 nm)/DCzPPy:FIrpic (13%):Ir(absn)2(acac) (4%)/BmPyPB/LiF/Al exhibited an external quantum efficiency of 10.7%, a power efficiency of 23.0 lm/W, a very high color rendering index of 88.1, and a correlated color temperature of 2629 K at 1,000 cd/m2. |
