Photocurrents of a ruthenium dye-TiO(2) system are enhanced by gold nanoparticles (100 or 40 nm diameter) embedded in TiO(2). As dye-particle spacing decreases to 10 nm, enhancement factor and intensity of localized electric fields at the TiO(2) surface increase. A further decrease in the spacing suppresses the enhancement.
金纳米粒子（直径为 100 或 40nm）嵌入二氧化钛（TiO2）中，增强了钌染料-TiO2 体系的光电流。当染料-颗粒间距减小至 10nm 时，TiO2 表面的局域电场增强因子和强度增加。进一步减小间距会抑制增强。
