Abstract :
We report on the photophysical properties of blends of poly(2-methoxy-5-(2′-ethyl-hexyloxy)-p-phenylene vinylene), MEH-PPV, and perylene bis(phenethylimide), PPEI. Highly efficient quenching of photoluminescence (PL) efficiency was observed. We have measured the photocurrent response of an MEH-PPV/PPEI blend in a sandwich cell between indium tin oxide (ITO) and aluminium electrodes. The external quantum efficiency (EQE) is enhanced considerably with regard to single layer MEH-PPV devices.
