Abstract

In addressing the use of noble metal-dressed carbon nanotubes (CNTs) as a substrate for surface enhanced Raman scattering (SERS) we re-direct attention from interactions at the outer interface with deposited molecular species to interactions at the inner (silver-CNT) interface and the extraction of enhanced D- and G-band signals from the CNTs themselves. This offers a means for reliable, Raman-based characterization of vertically aligned CNTs at a sensitivity improved by over an order magnitude; obtaining data from individual CNTs is readily achievable. Experimental data will be interpreted with the assistance of electromagnetic modelling of the optical response.
