Abstract

We simulated the extinction spectra of Ag–Au alloyed nanoparticles produced by pulsed laser ablation in liquid of elemental targets followed by re-irradiation of suitable mixtures of the obtained colloidal suspensions. When we make use of the optical constants of Ag–Au alloys, our theoretical approach, developed in the framework of the T-matrix formalism, accurately reproduces the experimental features of the extinction spectra of laser-produced nanoalloys with compositions that span the entire composition range (Ag25Au75, Ag50Au50, and Ag75Au25).

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.
