| 英文摘要 | in this work, organic electroluminescent (el) devices with dominant and supplementary light-emitting layers (emls) were designed to further improve the el performances of two iridium(iii)-based phosphorescent complexes, which have been reported to provide el devices with slow el efficiency roll-off. the widely used hole-block material 2,2',2 ''-(1,3,5-benzinetriyl)-tris(1-phenyl-1-h-benzimidazole) (tpbi) was selected as host material to construct the supplementary evil. compared with single-eml devices, double-emls devices showed higher el efficiencies, higher brightness, and lower operation voltage attributed to wider recombination zone and better balance of carriers. in addition, the insertion of supplementary evil is instrumental in facilitating carriers trapping, thus improving the color purity. finally, high performance blue-green and green el devices with maximum current efficiencies of 35.22 and 90.68 cd/a, maximum power efficiencies of 26.36 and 98.18 lm/w, and maximum brightness of 56,678 and 112,352 cd/m(2), respectively, were obtained by optimizing the doping concentrations. such a device design strategy extends the application of a double eml device structure and provides a chance to simplify device fabrication processes.
