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.
