Abstract

The infrared extinction properties of gold nanocrescents fabricated using nanosphere template lithography were studied. The nanocrescents exhibit multiple, structurally tunable localized surface plasmon resonances (LSPRs) across a broad spectral range (560-3600 nm). Plasmon resonances in the infrared have large extinction efficiencies of ∼20 and peaks as narrow as 0.07 eV. The nanocrescents also have high refractive index sensitivities (370-880 nm/RIU) that are proportional to the LSPR wavelengths. The sensing figure of merit measured for ensembles of nanocrescents is as high as 2.4 for near-infrared plasmon resonances.
