Mapping SERS in CB:Au Plasmonic Nanoaggregates
Source abstract
Abstract
In order to optimize surface-enhanced Raman scattering (SERS) of noble metal nanostructures for enabling chemical identification of analyte molecules, careful design of nanoparticle structures must be considered. We spatially map the local SERS enhancements across individual microaggregates comprised of monodisperse nanoparticles separated by rigid monodisperse 0.9 nm gaps and show the influence of depositing these onto different underlying substrates. Experiments and simulations show that the gaps between neighboring nanoparticles dominate the SERS enhancement far more than the gaps between nanoparticles and substrate.
