Abstract
We report the observation of photoluminescence quenching in thin films of poly(3-hexylthiophene) and Langmuir-Blodgett-films of poly(3-hexylthiophene)/arachidic acid by the injection of positive charges in the polymer. Charge injection was made in a polymer field effect transistor. The quenching is discussed in terms of polarons and/or bipolarons acting as recombination centers for the excitons, suppressing the photoluminescence.
