Surface-Enhanced Raman Scattering Spectra of Radial Breathing and G Band Modes in Functionalised Nanotubes

Abstract

In this Letter we perform surface enhanced Raman scattering studies of two functionalised nanotubes, an oxidised SWCNT and a SWCNT with a fluorescein side group covalently attached to the nanotube was compared with pristine SWCNTs. Our studies showed that in the GÀ band a significant shift was seen, while relatively little change occurred in the G+ and RBM spectral regions. These results indicate that SERS is broadly in line with Raman studies of chemically altered SWCNTs.
