Abstract: "Spectrofluorimetric
measurements on single-walled carbon nanotubes (SWNTs) isolated in aqueous
surfactant suspensions have revealed distinct electronic absorption and
emission transitions for more than 30 different semiconducting nanotube
species. By combining these fluorimetric results with resonance Raman data,
each optical transition has been mapped to a specific (n,m) nanotube
structure. Optical spectroscopy can thereby be used to rapidly determine the
detailed composition of bulk SWNT samples, providing distributions in both
tube diameter and chiral angle. The measured transition frequencies differ
substantially from simple theoretical predictions. These deviations may
reflect combinations of trigonal warping and excitonic effects."
