In this presentation, efficient white polymer-light-emitting diodes have been fabricated with high work-function cathode. The device structure consists of ITO/poly(ehtlenedioxythiophene) : poly(styrene sulfonic acid) (PEDOT : PSS) / poly(N-vinylcarbazole) (PVK) / poly[(9,9-bis(30-(N,N-dimethylamino)propyl)-2,7-fluorene)-alt- 2,7-(9,9-dioctylfluorene)] (PFN): bis(2-(4,6-difluorophenyl)-pyridinato-N,C2') picolinate (FIrpic): poly[2,7-(9,9-dioc-tylfluorene)-co-(4,7-dithien-2-yl)-2,1,3-benzothiadiazole] (PFODBT15)/Al. By tuning the weight ratio of FIrpic to PFO-DBT15 in PFN, white light was obtained. The 1931 CIE coordinates of the white lights obtained were (0.37, 0.41) and (0.36, 0.42). The maximum luminous efficiency was 3 cd/A.
