Research Abstract

(1) 紫外～近赤外領域に明瞭な表面プラズモン共鳴(SPR)吸収を示す無機ナノ粒子の一次(粒径、形状、組成)・二次構造(粒子間距離、配列様式)をナノスケールで精密制御することにより、紫外～近赤外領域(200～2000nm)で波長チューニング可能な光電場増強空間を構築する。さらに、この波長可変光電場増強空間による光学禁制遷移の直接誘起について検討する。
(2) プラズモンナノ粒子および半導体ナノ粒子からなるヘテロ接合ナノ粒子を合成・配列し、プラズモン誘起光電場増強による金属から半導体への電子移動を実現することで、半導体ナノ粒子表面での高効率可視光還元反応や光電変換反応を行う。
