US 10,118,833 B2 · Dimensionally focused nanoparticle synthesis methodology

Abstract

A methodology for synthesizing a nanoparticle batch, such as but not limited to a metal chalcogenide nanoparticle batch and further such as but not limited to a metal sulfide nanoparticle batch is predicated upon an expectation and observation that at elevated concentrations of at least one reactant material within a heat-up nanoparticle batch synthesis method, the resulting nucleated batch comprises nanoparticles that may be dimensionally focused to provide a substantially monodisperse nanoparticle batch. The embodied methodology is also applicable to a continuous reactor. The embodied methodology also considers viscosity as a dimensionally focusing result effective variable.

Dependent claims

A nanoparticle synthesis method comprising:

mixing together at a first temperature at least:
a first reactant material at a first concentration;
and
a second reactant material at a second concentration, to provide a reactant composition,
wherein the first reactant material is present at 50% or greater of the saturation limit of the first reactant material and/or the second reactant material is present at 50% or greater of the saturation limit of the second reactant material;
thermally adjusting the reactant composition to a second temperature to provide a nucleated virgin nanoparticle population within a nucleated reactant composition;
and
thermally soaking the nucleated virgin nanoparticle population in the nucleated reactant composition to provide a substantially monodisperse nanoparticle population.
