A series of white organic light-emitting devices(OLEDs) using multi-layer structures,containing a novel material((E)-2-(2-bromo-4-fluorostyryl)quinolato-Zinc,BFHQZn) as yellow emitting layers and ADN blue emitting layers,were fabricated.The effect of CBP on CIE coordinates was studied.The device structure is ITO/2T-NATA(15 nm)/NPBX(5 nm)/CBP:13%ADN(15 nm)/BFHQZn(20 nm)/CBP:6%Ir(ppy)3(5 nm)/CBP:13%ADN(15 nm)/BCP(8 nm)/Alq3(32 nm)/LiF(0.5 nm)/Al.The maximum luminance of 3 323 cd/m2(at 15 V) and the maximum lu...
