Transparent white organic light-emitting devices with a LiF/Yb:Ag cathode are reported. The device with a structure of indium-tin oxide/ 4,4('),4('') -tris(3-methylphenyl-phenylamino)-tripheny-lamine (40 nm)/N,N(')-bis-(1-naphthyl)- N,N(') -diphenyl- 1,1(')-biph-enyl-4,4(')-diamine (NPB: 7 nm)/rubrene (0.1 nm)/NPB(3 nm)/2,2('),2('')-(1,3,5-phenylene) tris(1-phenyl- 1H- benzimidazole (30 nm)/tris (8-hydroxyquinoline) aluminum (20 nm)/LiF(0.5 nm)/Yb:Ag (15 nm, volume ratio 1:1) shows few differences in luminance and color purity from both sides. For instant, at a driving voltage of 10 V, the luminance and CIE coordinates of 1173/1488 cd/m(2) and (0.3482,0.3596)/(0.3508,0.3352) are obtained from top/bottom sides. CIE coordinates of the device from both sides are voltage independent, and the maximum total electroluminescence efficiencies of the device are 4.6 cd/A.
报道了具有LiF/Yb:Ag阴极的透明白色有机发光器件。具有氧化铟锡/4,4′,4″-三(3-甲基苯基-苯基氨基)-三苯胺(40纳米)/N,N′-双-(1-萘基)-N,N′-二苯基-1,1′-联苯-4,4′-二胺(NPB:7纳米)/红荧烯(0.1纳米)/NPB(3纳米)/2,2′,2″-(1,3,5-亚苯基)三(1-苯基-1H-苯并咪唑)(30纳米)/三(8-羟基喹啉)铝(20纳米)/LiF(0.5纳米)/Yb:Ag(15纳米，体积比1:1)结构的器件从两侧的亮度和色纯度几乎没有差异。例如，在10伏的驱动电压下，从顶部/底部获得的亮度和CIE坐标分别为1173/1488坎德拉每平方米和(0.3482,0.3596)/(0.3508,0.3352)。器件两侧的CIE坐标与电压无关，该器件的最大总电致发光效率为4.6坎德拉每安培。
