Abstract
Sonochemical synthesis methods of particles (e.g., nanoparticles, microparticles, quantum dots) in emulsion reaction mixtures are described herein. The methods allow for control of the bulk temperature of the reaction mixtures to minimize the effects of solvent temperature increases. The sonochemical synthesis methods (e.g., in emulsion reaction mixtures) offer efficient, accelerated, and controllable pathways towards the on-demand synthesis of complex materials.
Claims26
A sonochemical method of making particles, comprising:
- providing an emulsion comprising uniformly dispersed immiscible droplets in a continuous phase, and one or more particle precursors;
- exposing the emulsion to ultrasound irradiation having a frequency of at least 20 kHz to nucleate and form particles in the emulsion, without increasing an emulsion bulk temperature in excess of 50° C.;
- and
- isolating the particles from the emulsion,
- wherein when the emulsion is an aqueous emulsion, the particle precursors do not comprise a gold salt.
