| 中文摘要 | we report an efficient non-doped all-polymer polymer white-light-emitting diode (pwled) with a fluorescent three-color, white single polymer as an emissive layer, an ethanol-soluble phosphonate-functionalized polyfluorene (pf-ep) as an electron-injection/electron-transport layer, and lif/al as a cathode, respectively. the all-polymer pwled achieves a peak external quantum efficiency of 6.7%, a forward viewing luminous efficiency of 15.4 cd a(-1) and a power efficiency of 11.4 lm w-1, respectively, at a brightness of 347 cd m(-2) with commission internationale d'eclairage coordinates of (0.37, 0.42) and color rendering index of 85, which is the best results among the non-doped pwleds. moreover, this kind of pwled not only shows excellent color stability, but also achieves high brightness at low voltages. the brightness reaches 1000, 10000, and 46830 cd m(-2) at voltages of 4.5, 5.4, and 7.5 v, respectively. the significant enhancement of white-single-polymer-based pwleds with pf-ep/lif/al to replace for the commonly used ca/al cathode is attributed to the more efficient electron injection at pf-ep/lif/al interfaces, and the coordinated protecting effect of pf-ep from diffusion of al atoms into the emissive layer and exciton-quenching near cathode interfaces. the developed highly efficient non-doped all-polymer pwleds are well suitable for solution-processing technology and provide a huge potential of low-cost large-area manufacturing for pwleds. |
