dc.descriptionPhotoluminescence (PL) measurements of porphyrin-doped single wall carbon nanotubes (SWNT) were studied in sodium dodecylbenzenesulfonate (NaDDBS) aqueous dispersions. The PL spectra were used to draw PL maps were the maxima corresponds to absorption-emission excitonic processes related to (E11, E22) first Van Hove singularities of the SWNT electronic structure. The influence of the net charge of the porphyrin was a determinant factor in the energy map maximum shifts (EMMS) compared to the energy map of a pristine NaDDBS/SWNT dispersion. A non-interacting porphyrin is used as a reference to discard the influence of the dielectric constant of the medium in the EMMS.
