To enhance the efficiency of polymer light-emitting diodes, the polymer is often doped with a triplet emitter. In order to obtain a blue-emitting material, PVK and PEPK are chosen as fluorescent polymer matrices for blue-emitting CdSe/ZnS quantum dots (QDs), encapsulated with a carbazole-terminated ligand. The better miscibility and less extensive excimer formation enhance the efficiency of both singlet and triplet energy transfers to the QDs significantly in PEPK compared to PVK.
