- PublicationSurface-enhanced Raman scattering spectra of radial breathing modes and G+/- bands in functionalised nanotubes(Elsevier, 2013-05)
; ; ; ; ; In this paper 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 G- 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.419Scopus© Citations 4 - PublicationSurface-enhanced Raman scattering from small numbers of purified and oxidised single-walled carbon nanotubes(Elsevier, 2012-05-11)
; ; ; ; Surface enhanced resonance Raman scattering (SERRS) has been applied to investigate defects in purified and carboxylated single-walled carbon nanotubes (SWCNTs). For both samples SERRS spectra with temporal fluctuating peak intensities and positions in the range of 1000 to 1350 cm-1 have been observed. A series of peaks in this window were observed to coincide with peak positions that have been assigned to arise from Stone-Thrower-Wales and heptagonal-pentagonal intramolecular junction defects on the nanotubes surface. Two possible origins for these fluctuating spectral features are discussed ie the presence of Stone-Thrower-Wales defects in SWCNTs or amorphous carbon impurities.Scopus© Citations 27 495
