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

摘要

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.
