Abstract

Raman spectroscopy is used to probe the structure and electronic properties of nanotubes dispersed in a liquid phase. We show that the radial breathing modes are upshifted in suspensions due to the molecular pressure of the solvent. On the other hand, we directly probe charge transfer in solutions of nanotube polyelectrolytes and its reversibility after oxydation in air.

[19] This is always true for aqueous supensions prepared with the non-ionic surfactant Triton X100. By contrast, we observed signatures of doping in the Raman spectra of aqueous suspensions prepared with SDS, which we assigned to charge transfer between SWNT and SO4 2- species (to be discussed elsewhere).Google Scholar
