用气相沉积法制备了1，4-双(2，2-二苯基乙烯)联苯与4-(dicyanomethylene)-2-methyl-6-(julolidin-4-yl-vinyl)-4H-pyran和/或10-(2-benzothiazolyl)-2，3，6，7-tetrahydro-1，1，7，7-tetramethyl-1H，5H，11H-(1)benzopy-rano(6，7，8-l，-j)喹啉-11-酮的混合溶剂，制备了高效、稳定的单发光层白色荧光有机电致发光器件。当功率密度为100cd/m2时，两光谱纯白光OLED的功率效率为4.6 lm/W，三光谱白光OLED的功率效率为7.2 lm/W m2。用10，10‘-二(联苯基-4-基)-9，9’-联菲和绿蓝染料二(三苯胺)-1，4-二乙烯基萘作为基质，获得了功率效率为6.8 lm/W的三光谱有机电致发光器件，功率密度为100cd/m2。
Efficient, color-stable fluorescent white organic light-emitting diodes (OLEDs) with single emission layer were fabricated by vapor deposition from solvent premixed mixtures of 1,4-bis(2,2-diphenylvinyl)biphenyl doped with 4-(dicyanomethylene)-2-methyl-6-(julolidin-4-yl-vinyl)-4H-pyran and/or 10-(2-benzothiazolyl)-2,3,6,7-tetrahydro-1,1,7,7-tetramethyl-1H,5H,11H-(1)benzopy-rano(6,7,8-l, j)quinolizine-11-one. The power efficiencies at 100 cd/m2 were 4.6 lm/W for the two-spectrum pure white OLEDs and 7.2 lm/W m2 for the three-spectrum ones with white emission. By using a different host of 10,10′-bis(biphenyl-4-yl)-9,9′-bianthryl and a greenish-blue dye of di(triphenylamine)-1,4-divinylnaphthalene, the three-spectrum OLEDs with a power efficiency of 6.8 lm/W at 100 cd/m2 were obtained.
