A method to correlate optical properties and structures of metallic nanoparticles.
The optical response of individual nanoparticles is strongly influenced by their structures. In this report, we present a quick and simple pattern-matching based approach in which optical images of nanoparticles from localized surface plasmon resonance and single-molecule surface-enhanced Raman spectroscopy were used in conjunction with transmission electron microscopy for correlation of optical responses and the nanostructures of exactly the same nanoparticles or clusters of nanoparticles.
