Abstract | We realize high luminous efficiency (LE) in white polymer light-emitting devices by employing a wide bandgap polymer P36HCTPSÍ as host and introducing a blue-yellow two-color system for obtaining white emission. Phosphorescent dopants bis[(4,6-difluorophenyl)pyridinato-N,C 2′]-(picolinato)iridium(III) (FIrpic) and iridium(III) bis(2-(9,9′-spirobi[fluorene]-7-yl)pyridine-N,C2′) acetylacetonate [Ir(SBFP)2 (acac)] were used as blue and yellow emitters, respectively. Electroluminescent spectra and LE were both affected by Ir(SBFP)2 (acac) concentration; the device with low concentration (0.4 wt.%) showed white emission with a LE of 24.1 cd/A at 1000 cd/m 2, while the one with high concentration (4 wt.%) emitted yellowish-white light with a higher LE of 47.3 cd/A at 1000 cd/m2. © 2010 Optical Society of America. |
