FDSERS17 Electrochemical Control of Strong Coupling States Between Localized Surface Plasmons and Molecule Excitons for Raman Enhancement

Abstract

The intensity of Raman scattering from dye molecules strongly coupled with localized surface plasmon of metal nanostructures was controlled by electrochemical potential. Through in-situ electrochemical extinction and surface enhanced Raman scattering measurements, the redox state of the molecules affect to the coupling strength, leading to the change in the intensity of Raman scattering. The analysis of Raman spectrum provides the information on the molecules in the strong coupling state showing effective enhancement of Raman scattering.
