Abstract
We report the results of absorption and photoluminescence (PL) studies on s olutions and films of the soluble PPV derivative poly (p-phenylenevinylene- co(2,5-dioctyl)p-phenylene vinylene) (PPV-co-DOctPV). The PL is broadened a nd red shifted in the film and we have investigated the role of solvent on the optical characteristics. The possibility of aggregation has been invest igated using photoluminescence excitation spectroscopy. We report measureme nts of the effect of excitation intensity on the photoluminescence (PL) spe ctrum and observe spectral line narrowing.
