Thermodynamic Control of Gold Nanocrystal Size: Experiment and Theory

Leff, Daniel V., Ohara, Pamela C., Heath, James R., Gelbart, William M.·1995·The Journal of Physical Chemistry

Abstract

We present an experimental demonstration and a corresponding statistical thermodynamic formulation of \nsurfactant-mediated size control of Au nanocrystals. In particular, we show how particle size-over a range of diameters from 15 to 200 A-can be sensitively controlled by simply varying the gold-to-thiol ratio. The agreement between theory and experiment is confirmed by X-ray line-broadening measurements of the nanocrystal products from a room-temperature synthesis in which the gold-thiol composition is systematically varied.

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.
