中文摘要	a semitransparent white organic light-emitting diode (woled) is produced based on a blue phosphorescence from iridium(iii)[bis(4,6-difuorophenyl)-pyridinato-n,c-2] picolinate and an orange phosphorescence from bis(2-(9,9-diethyl-9h-fluoren-2-yl)-1-phenyl-1h-benzoimidazol-n,c-3) iridium(acetylacetonate). in this work, a hole-transporting layer of n,n'-diphenyl-n,n'-bis (1-naphthylphenyl)-1,1'-biphenyl-4,4'-diamine (npb) and an electron-transporting layer of 3,5,3 '',5 ''-tetra-3-pyridyl-[1,1';3',1 ''] terphenyl (b3pypb) were used. b3pypb has high electron mobility and a high triplet energy level. the use of b3pypb helps to reduce the triplet quenching and also to confine the charge recombination in the emissive region of a single-host two-color woled. a bi-layer ag (10 nm)/moo3 (2.5 nm)-modified indium tin oxide anode and a cathode of al (1.5 nm)/ag (15 nm)/npb (50 nm) were employed. the semitransparent woleds thus developed have perfect symmetrical, bi-directional illumination characteristics, and the weak angular dependent el emission spectra, which are beneficial for application in planar diffused lighting.
