| Research Abstract |
We observed the resonant rayleigh scattering of lowest exciton transition of single walled carbon nanotubes grown on the optical nanofiber which is one of the possible structures of generating localized light field. The exciton linewidth (~1meV) observed by rayleigh scattering is sharper than the exciton linewidth observed by photoluminescence. The photoluminescence quantum yield of PFO dispersed carbon nanotubes is limited by the shortening of nanotubes due to vigorous sonication. We also clarified the fundamental optical properties of carried-doped carbon nanotubes that are expected to show the large response to optical field.
