Abstract

The visible light-response plasmonic photocathodes were established by depositing Au nanorod structures on wide band gap semiconductor electrodes. By using Au nanorods showing multicolor response characteristics, we observed the generations of the photocurrent under multicolor light illuminations. Additionally, we successfully estimated the absolute electrochemical potential of the excited electrons through the photoinduced depositions of metal species. Our important finding is that the electrochemical potential of the reactive electrons changes not only with the wavelength of illuminated light but also with the semiconductor substrates. Insights from our current findings can be used to develop highly efficient systems for converting light into energy.
