dc.description.abstract | We have demonstrated an optimized polymeric host material comprising a blend of poly (9-vinylcarbazole) (PVK) and a fluorescent polymer for a highly efficient electrophosphorescence system. Although the chemical compatibility between the blue-emitting-fluorescent polymer and iridium complex, tris[2-phenylpyridine]iridium(III) (Ir-(ppy)(3)) is very poor, efficient energy transfers from the blended host to the Ir complex was observed when a small amount of blue-emitting-fluorescent polymer was added to the PVK matrix. The device showed a maximum external quantum efficiency at 5 wt% blue-emitting-fluorescent polymer and 8 wt% Ir complex doping concentrations. (C) 2008 Elsevier B.V. All rights reserved. | - |
