Wavelength- and efficiency-tunable plasmon-induced charge separation by the use of Au–Ag alloy nanoparticles

Author affiliations

Abstract

TiO2 electrodes loaded with Au–Ag alloy nanoparticles, Ag content of which is about 0.25–0.90, exhibit stable anodic photocurrents due to plasmon-induced charge separation (PICS) in the presence of an electron donor. The PICS wavelength is blueshifted and the PICS efficiency is enhanced by increasing the Ag content in the nanoparticles.
