Abstract
We report on surface-enhanced Raman scattering (SERS) from bundles of size- selected single-wall carbon nanotubes (SWCNTs) deposited on ordered arrays of silver- and gold-coated silica spheres. Selective enhancement of the Ram an-active tangential and radial modes of SWCNTs is exhibited in backscatter ing at surface plasmon resonance conditions. Enhancement at plasmon wavelen gth and sub-wavelength is shown for various periodic pitches of the substra tes used. (C) 2001 Published by Elsevier Science B.V.
