Measuring ensemble-averaged surface-enhanced Raman scattering in the hotspots of colloidal nanoparticle dimers and trimers.
We report ensemble-averaged measurements of colloidal hotspots enabled by the synthesis of highly uniform dimers and trimers of Au@Ag nanoparticles and the quantification of the relative concentrations of the nanoclusters.
