    Abstract

    The fabrication of copper phthalocyanine (CuPc)-gold nanorod (AuNR) composite films on indium-tin-oxide electrodes was performed by electrostatic layer-by-layer adsorption technique. The photocurrents in CuPc-AuNR composite films were larger than those in CuPc films as a reference. The enhancements of the photocurrents in CuPc-AuNR composite films due to AuNR increased with increasing of wavelength up to near-infrared region. The enhancements are attributable to localized surface plasmon resonance (LSPR) due to AuNR. The enhancements at near-infrared wavelength due to the longitudinal LSPR were larger than those at visible wavelength due to the transverse LSPR.
