AbstractThe localized surface plasmon resonance (LSPR) is a collective oscillation of conduction electrons confined in metal nanostructures and is largely responsible for surface enhanced spectroscopies. Surface enhanced Raman scattering (SERS) is the best known and most widely applied example of such a surface enhanced spectroscopy. Although closely related and complementary to SERS, surface enhanced infrared absorption (SEIRA) spectroscopy requires more careful engineering of the LSPR of metal nanostructures so that the resonance is within the mid-infrared region. In this study, we demonstrate the use of gold nanorods (Au NR) as a suitable substrate capable of sustaining strong SEIRA spectroscopy. Adsorbate saturated Au NR typically exhibit Fano-type resonances in their SEIRA spectra obtained using reflectance FTIR. Such line asymmetry occurs due to the coupling of the relatively sharp molecular vibrations to the broad continuum of the LSPR resonance of the aggregated Au NR. © 2011 Materials Research Society.
