Outline of Final Research Achievements

Metal nanoparticles exhibit localized surface plasmon resonance (LSPR). It generates near-field light around the surface of the particle with resonant light irradiation. In this study, I developed photon to chemical energy conversion systems, which can utilize light with weak energy.
First, I investigated the effective combination way with dyes and metal nanoparticles by measuring photocurrents. On the basis of the results, I developed site-selective nanoscale polymerization method which can fabricate polymeric dyes on the surface of metal nanoparticles site-selectively via plasmon induced charge separation (PICS) by using near-infrared light which is the light with weak energy as a light source.
