Highly Tunable Infrared Extinction Properties of Gold Nanocrescents
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 approximately 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.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
