Abstract

We investigated the enhancement properties of the photocurrent generation from self-assembled monolayers of porphyrin fabricated on periodic structures of gold half-shells. Tuning the surface plasmon frequency of the nanostructures led to correlated wavelength dependences of the external quantum efficiencies of the photocurrents, as well as fluorescence intensities resulting from effective electronic excitation of porphyrin molecules.
