Paper Abstract

We study theoretically and experimentally the variation in localized surface plasmon resonance (LSPR) structure (λmax=660 nm) as a function of dielectric coating thickness. The influence of the morphology and interparticle distance on the LSPR spectra of a glass/Au NSs interface with a constant thickness of diamond (NCD) overcoating was investigated through the calculation of theoretical transmission spectra. Ajusting the theoretical curve to experimental LSPR spectra allowed fixing the geometry of the plasmonic interface and permitted to evaluate the change in the wavelength at maximum absorption (λmax) as a function of the thickness of the NCD overlayers. The theoretical data were compared with experimental ones obtained on glass/AuNSs/ NCD surface.
