| Outline of Final Research Achievements |
The photocurrents in copper phthalocyanine (CuPc)-gold nanorod (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.
Second Harmonic Generation (SHG) in dye (stilbazolium derivative; C18Stil or Azobenzene derivative; C12Azo)-AuNR composite films were measured. The SH light intensities in C18Stil-AuNR composite films decreased as compared with those in C18Stil films. Also the SH light intensities in C12Azo-AuNR composite films were slightly enhanced as compared with those in C12Azo films.
