| 제목 | White emission from conjugated polymer blended with phosphorescent dye via efficient energy transfer |
| 초록 | We studied single-layer white organic light-emitting devices (WOLEDs) based on phosphorescent dye in polymer matrix. The electroluminescent spectra of the device consisted of blue and green fluorescent from the matrix and red phosphorescent emission. In the device, partial energy transfer occured in active layer not only from blue to green and red but also from green to red. White emission was obtained by optimizing the concentration of consisting components. The driving voltage of the device was decreased because the energy of blue conjugated polymer was directly transferred to red phosphorescent dye efficiently with less charge trapping, and the intensity of the blue emission was increased gradually relative to the other emissions with increasing applied voltage.
