Efficient white polymeric light-emitting diodes by doping ionic iridium complex
|
Abstract:
A series of white polymer light-emitting diodes (WPLEDs) each with a single emitting layer using ionic iridium complex is fabricated.The white light is obtained via two complementary colors of orange light emitter ionic iridium complexe (npy)2Ir(c-phen)]PF6 (Hnpy:2-(naphthalen-1-yl)pyridine,c-phen:1-ethyl-2-(9-(2-ethylhexyl)-9H-carbazol-3-yl)-1H-imidazo4,5-f]1,10]phenanthroline) and sky-blue light emitter Firpic (iridium bis(2-(4,6-difluorophenyl)-pyridinato-N,C(2)) picolinate.The emtting layer consists ...
