Nonlinear spectroscopy and picosecond transient grating study of colloidal gold
Abstract
Measurements of the nonlinear dispersion of χ(3) have been performed on the surface plasmon resonance of aqueous colloidal gold. An analysis of the observed dispersion has revealed that the T1 and T2 lifetimes for the plasmon excitation are extremely rapid (<10−14 s) but the release of heat by the particle electron/thermal reservoir is slower (>2 ps). Picosecond time-resolved transient grating experiments on the same gold sol and organic dye solutions have confirmed that the nonradiative thermal decay of the metal particles occurs on the time scale of tens of picoseconds. The application of these methods to the study of ultrafast nonradiative relaxation mechanisms in molecular systems is discussed.

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.
