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.||Type of material:||Journal Article||Publisher:||Elsevier||Journal:||Chemical Physics Letters||Volume:||535||Issue:||11 May 2012||Start page:||146||End page:||151||Copyright (published version):||2012 Elsevier B.V.||Keywords:||Carbon nanotubes; SERs; Raman; Surface enhanced Raman; Impurities||DOI:||10.1016/j.cplett.2012.03.092||Language:||en||Status of Item:||Peer reviewed|
