Journal ArticleDOI
Gold particle interaction in regular arrays probed by surface enhanced Raman scattering
Nordin Félidj,S. Lau Truong,Jean Aubard,Georges Lévi,Joachim R. Krenn,A. Hohenau,A. Leitner,Franz R. Aussenegg +7 more
TL;DR: The simultaneous investigation of extinction and Raman spectra of arrays exhibiting various topography parameters enables us to suggest an interpretation for both the occurrence of the two plasmon resonances and for the high Raman enhancement.
Journal ArticleDOI
Evidence of multipolar excitations in surface enhanced Raman scattering
Guillaume Laurent,Nordin Félidj,Jean Aubard,Georges Lévi,Joachim R. Krenn,Andreas Hohenau,Gerburg Schider,Alfred Leitner,Franz R. Aussenegg +8 more
TL;DR: In this paper, it was shown that multipolar plasmon resonances can give rise to strongly enhanced spectra with an amplification per molecule similar to that obtained for dipolar Plasmon excitation.
Journal ArticleDOI
Thin films by regular patterns of metal nanoparticles: Tailoring the optical properties by nanodesign
TL;DR: In this article, the optical extinction maximum wavelength can be tuned in a range from 460 nm to 520 nm and the bandwidth between 50 and 100 nm by independent variation of particle shape and interparticle distance.
Journal ArticleDOI
Quantitative analysis of surface plasmon interaction with silver nanoparticles.
Andrey L. Stepanov,Joachim R. Krenn,Harald Ditlbacher,Andreas Hohenau,A. Drezet,B. Steinberger,Alfred Leitner,Franz R. Aussenegg +7 more
TL;DR: This work investigates a SPP beam splitter constituted by silver nanoparticles on a silver thin film, fabricated by electron-beam lithography, yielding SPP reflection, transmission, and scattering efficiencies.
Journal ArticleDOI
Grating-induced plasmon mode in gold nanoparticle arrays.
Nordin Félidj,Guillaume Laurent,Jean Aubard,Georges Lévi,A. Hohenau,Joachim R. Krenn,Franz R. Aussenegg +6 more
TL;DR: It is shown how this band associated to a grating induced-resonance can be influenced in strength and spectral position by systematically changing the particles dielectric environment, the particles shape, the grating constant and angle of incidence.
