제목 High performance white organic light-emitting diodes with blue fluorescence and red phosphorescence
초록 DAnP was synthesized and electrical properties were characterized. The PL maximum value of DAnP is 469nm in solution state and 480nm in film state. DAnP was used as non-doped emitting layers (EMLs) in OLEDs with the following structures: ITO/2-TNATA (60 nm)/NPB (15 nm)/DAnP (35 nm)/Alq3 (20 nm)/LiF (1 nm)/Al (200 nm). The EL maximum value is 480nm, which is similar to the result for the PL maximum value. The luminescence efficiency was 5.45 cd/A and power efficiency was 2.71 lm/W at 10mA/cm2. A efficient multilayer white organic light-emitting diode(WOLED) with the structure of ITO/NPB (30 nm)/CBP: 3 wt% Ir(piq)3 (8 nm)/DAnP (40 nm)/TPBi (40 nm)/ LiF (1 nm)/Al (200 nm) was fabricated and characterized, where DAnP and tris(1-phenylisoquinoline) iridium (Ⅲ) [Ir(piq)3] were used as a blue fluorescent dye and a red phosphorescent dye respectively. A WOLED showed luminance efficiencies of 5.08 cd/A, power efficiencies of 2.55 lm/W, and CIEs of (0.35, 0.36) at 10mA/cm2.
