Abstract

We report on two different approaches to modify the emission spectra of poly(phenyl-phenylenevinylene). By doping with different amounts of a laser dye, the fluorescence spectra shift to lower energies due to picosecond transfer of the excitations from conjugated segments of the polymer to the acceptor molecules. As an alternative approach we show that Fabry-Perot microcavities can be used to control and enhance the spontaneous emission of a conjugated polymer layer.
