First Observation Of The Raman Spectrum Of Isolated Single‐Wall Carbon Nanotubes By Near‐Field Optical Raman Spectroscopy

In this paper, we report the first observation of the Raman spectrum of isolated single‐wall carbon nanotubes (SWNTs) by near field optical Raman spectroscopy. Raman spectra have been obtained by using an aperture‐based scanning near field optical microscope (SNOM) which is coupled to a T64000 Jobin Yvon spectrometer in collection mode. Surface Enhanced Raman Scattering (SERS) effect is needed in order to amplify the scattered intensity.
