Abstract

Photocurrents of a ruthenium dye-TiO₂ system are enhanced by gold nanoparticles (100 or 40 nm diameter) embedded in TiO₂. As dye-particle spacing decreases to 10 nm, enhancement factor and intensity of localized electric fields at the TiO₂ surface increase. A further decrease in the spacing suppresses the enhancement.
