Tuning the emission color of polymer light-emitting devices (PLEDs) based on a conjugated polymer poly(9,9-dioctylfluorene) (PDOF) through the maskless dye diffusion technique has been studied. The introduction of a green-light-emitting dye, Coumarin 6, into PDOF through this technique results in green light emission from the PLEDs without notable alteration of the external quantum efficiency. On the other hand, the introduction of a red-light-emitting dye, Nile red, which generates pure red light in a poly(N-vinylcarbazole) matrix, results in a white light emission from the PLEDs with an external quantum efficiency smaller than the original device. The onset voltages of emission were almost doubled for both cases, suggesting that both dyes play a role of carrier trap in the polymer. For emission mechanisms, it was suggested that the former case be governed by the efficient energy transfer from PDOF to Coumarin 6 or the direct recombination in Coumarin 6, while the latter case may include exciplex formation.
