Research Abstract |
In our research project, we aim to enhance yields of photochemical reactions such as photochromism with a great assistance of localized surface plasmon. In a plasmonic nano-gap, an electromagnetic field of incident light should be loccalized at the gap. The main experimental method used in the present study is confocal micro-spectroscopy. So far, we have succeeded in achieving (i) plasmon-based-2-photon photochromic ring-opening reaction by irradiation of weak CW-NIR light, (ii) enhancement of 1-photon photochromic reaction, (iii) plasmon-based optical trapping of small nanoparticles, (iii) nano-hole processing by resonant plasmon excitation.
