中文摘要	we present a simple hybrid white organic light-emitting diodes (woled) consisting of only two layers, i.e., a hole-transporting layer and an emitting layer. the emitting layer is formed by simply co-doping a green phosphor and a red phosphor in bis[2-(2-hydroxyphenyl)-pyridine]beryllium (bepp(2)), which acts as the blue emitter, electron-transport material, and high triplet energy host for the phosphors, i.e., a multifunctional chromophore. this simple device exhibits a maximum power and quantum efficiency of 46.8 lm w-1 and 16.5%, respectively, with a good cri up to 90. the versatile experimental techniques are performed to gain a deep understanding of the emission mechanism. we believe that this simple design concept can provide a new avenue for achieving ultrahigh performance woleds for lighting application.
