Preparation of colloidal silver dispersions by the polyol process
Abstract
In a previous paper (J. Mater. Chem., 1996, 6, 573), we reported that colloidal silver dispersions can be synthezised by the polyol process, using an ethylene glycol–polyvinylpyrolidone (PVP) solution to reduce silver nitrate under precise temperature conditions. Quasi-spherical particles with a narrow size distribution were obtained. Low precursor and PVP concentrations, in contrast to high silver nitrate concentrations, were found to yield monodisperse systems with an average particle size of 15 to 21 nm. To understand the particle formation mechanism, the evolution of particle size and shape during the reaction was monitored by TEM and UV absorption spectroscopy techniques. An Ostwald ripening mechanism is proposed to account for the formation of the silver particles, even though the variation of temperature with time is not ideal for a complete mechanistic understanding.

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.
