Outline of Final Research Achievements

We developed a novel optical technique to elucidate the photothermal effect of metallic (plasmonic) nanostrucutures. Dark-field optical spectroscopy enabled us to determine surface temperature of the laser-illuminated metallic nanostructures. We also investigated the photothermal interactions of the metallic nanostructures with adsorbed organic molecules with the use of surface-enhanced Raman spectroscopy. These results have opened a new window in high temperature sciences.

Academic Significance and Societal Importance of the Research Achievements

光照射した貴金属ナノ構造表面の光誘起熱をプラズモン共鳴波長の変化として検出し、その光熱相互作用をナノ分光学的に測定した。この研究成果は、(1)従来の光熱加工法では不可能な10nm以下の熱加工分解能の実現、(2)従来の触媒化学では不可能なナノスケールでの触媒化学反応誘起とそのメカニズム解明に資するものであり、従来の『高温』を取り扱う研究分野の限界を打ち破るブレークスルーなりうる。
