Abstract
- In this paper, we report the surface-enhanced Raman scattering and normal Raman scattering from different parts of one individual single-walled carbon nanotube. We found that the intensity of radial breathing mode can be remarkably enhanced for surface-enhanced Raman scattering. And no frequency shift of the radial breathing mode has been observed. For the tangential mode at approximately 1590 cm(-1), the peak becomes slightly narrower for surface-enhanced Raman scattering. Both semiconducting and metallic nanotubes can be identified based on the line shape of tangential mode. Meanwhile, the intensities of tangential mode depend on laser excitation energies sensitively, which can be explained by different resonant transitional conditions.
