Journal ArticleDOI
Metallic Nanoparticle Arrays: A Common Substrate for Both Surface-Enhanced Raman Scattering and Surface-Enhanced Infrared Absorption
Fei Le,Daniel W. Brandl,Yaroslav A. Urzhumov,Hui Wang,Janardan Kundu,Naomi J. Halas,Javier Aizpurua,Peter Nordlander +7 more
TL;DR: Nanoshell arrays have recently been found to possess ideal properties as a substrate for combining surface enhanced raman scattering (SERS) and surface enhanced infrared absorption (SEIRA) spectroscopies, with large field enhancements at the same spatial locations on the structure.
Journal ArticleDOI
Fano Resonances in Plasmonic Nanoclusters: Geometrical and Chemical Tunability
J. Britt Lassiter,Heidar Sobhani,Jonathan A. Fan,Janardan Kundu,Federico Capasso,Peter Nordlander,Naomi J. Halas +6 more
TL;DR: It is shown that clusters of plasmonic nanoparticles and nanostructures support Fano resonances, and that this spectral feature, produced by the interference between bright and dark modes of the nanoparticle cluster, is strongly dependent upon both geometry and local dielectric environment.
Journal ArticleDOI
Tailoring plasmonic substrates for surface enhanced spectroscopies
Surbhi Lal,Nathaniel K. Grady,Janardan Kundu,Carly S. Levin,J. Britt Lassiter,Naomi J. Halas +5 more
TL;DR: This tutorial review outlines the design of metallic nanostructures tailored specifically for providing electromagnetic enhancements for surface enhanced Raman scattering (SERS) and the concepts developed for nanoshell-based substrates can be generalized to other nanoparticle geometries and scaled to other spectroscopies.
Journal ArticleDOI
Surface enhanced infrared absorption (SEIRA) spectroscopy on nanoshell aggregate substrates
TL;DR: In this paper, a statistical evaluation of aggregate geometries combined with finite difference time domain modeling of the infrared hot spots characteristic of the constituent structures was performed for surface enhanced infrared absorption (SEIRA) spectroscopy.
Journal ArticleDOI
Plasmonic Nanoshell Arrays Combine Surface‐Enhanced Vibrational Spectroscopies on a Single Substrate
TL;DR: A specifically designed, subwavelengthstructured metallic substrate that simultaneously enhances two complementary vibrational spectroscopies, namely, Raman scattering and infrared absorption spectroscopy, by introducing plasmon resonances in the two diverse frequency regions required for both spectroscopic enhancements.
