| Outline of Final Research Achievements |
In the last decade, enhancement of optical response using localized surface plasmon resonance (LSPR) is expected to have an effect of improving efficiency of wide variety of photochemical reactions using sunlight. The purpose of this research is to clarify the enhancement mechanism of photochemical reactions using LSPR. Here we succeeded the surface enhanced Raman scattering (SERS) measurement for single-molecule 4-aminobenzenethiol (4-ABT) on the single silver nanoaggregate, which molecule is one of the most important target for understanding of plasmon-based photochemical reactions. We first found that single-molecule SERS spectrum of 4-ABT shows unexpected peaks probably from Raman forbidden modes of 4-ABT and this result gives us the basis of clarification for the strong coupling regime between plasmon and molecule during the plasmon-based photochemical reactions.
