利用LiF/Mg阴极加强电子注入工艺，实现了基于铕配合物的高效、窄谱宽亮红色有机电致发光器件的制备。研制出了外量子效率超过1%、光输出大于320 cd/m2的器件。虽然在100 cd/m2的外部量子效率相当，但发光效率比最近基于磷光染料ptep的最先进设备高2.6倍。
The fabrication of efficient and bright red light-emitting organic electroluminescent devices based on Eu-complex, having narrow spectral width, is achieved by enhancing the electron injection process through the use of LiF/Mg cathode. Devices with external quantum efficiency exceeding 1% and light output higher than 320 cd/m2 are presented. While the external quantum efficiency at 100 cd/m2 is comparable, the luminous efficiency is 2.6 times higher than that of the recent state-of-the-art devices based on the phosphorescent dye PtOEP.
