Abstract
We report on a study of photoexcitation of single wall carbon nanotubes (SWNTs) and C
60-doped
π-conjugated polymers. We have studied the photoinduced charge transfer (PCT) in two poly(
p-phenylene vinylene) (PPV) derivatives (MEH-PPV and PmPV) as pure polymer and when doped with SWNTs or C
60. Using photoluminescence (PL) and photoinduced absorption (PA), we found evidence for PCT in the photoexcited PPV derivative composites and no significant interaction in the ground state. Evidences for PCT are supported by a reduction of the PL emission from the polymer in the composite films, an increase of the polarons in the polymer composites and C
60
− PA bands.
