Optical Absorption Study of the Surface Plasmon Resonance in Gold Nanoparticles Immobilized onto a Gold Substrate by Self-Assembly Technique
Abstract
The resonance wavelength of the surface plasmon in gold nanoparticles above a gold substrate has been measured using transmission absorption spectroscopy. Gold nanoparticles with diameters in the range of 20−100 nm are immobilized onto a thin gold film deposited onto a glass substrate by a self-assembled monolayer of aminoethanethiol. The resonance wavelength obtained in the experiments shows a large red shift. Its dependence on the particle diameter shows good agreement with theoretical results that are calculated using a static approximation that includes multipole effects.

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.
