Abstract

Spectroscopy of near-single molecular surface enhanced resonant Raman scattering (SERRS) of single plasmonic nanoparticle (NP) systems like NP dimer revealed that such systems are in strong coupling regimes between plasmon resonance and molecular exciton. We firstly show the evidence of strong coupling between plasmon and molecular exciton by calculation of classical electromagnetism. Secondly, we show reproduction of SERRS with surface enhanced fluorescence (SEF) spectra of dye molecules in the gaps of dimers under strong coupling conditions. By the way, the electronic structure of molecules in the strong coupling system is expected to be modulated by vacuum electromagnetic fields under the near single dye molecule condition. Thus, we finally show absorption spectroscopy of single strong coupling systems by combining extinction with scattering spectroscopy.
