摘要: 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 localized electric fields at the TiO2 surface increase. A further decrease suppresses enhancement.
