Paper Abstract

High resolution cw photoluminescence spectroscopy, energy transfer studies, time and spectrally resolved fluorescence decay as well as quenching of photoluminescence by strong electric fields support the notion that photon absorption in PPV-type conjugated polymers creates neutral excitations. They undergo a random walk among segments of the polymer chain thereby relaxing energetically. In the presence of an electric field they can form off- chain geminate pairs acting as precursors for free charge carriers.
