US Patent 7927516 - Microwave synthesis of semiconductor nanocrystals


This patent is based on research conducted within the University of California system and teaches high throughput production of quantum dots having uniform diameter. Claim 1 reads:

1. A method for chemically synthesizing nanoparticles, comprising

a heating process of a reaction system, which comprises precursors, passivants, and/or solvents in a reactor,

wherein microwave irradiation is used for the heating process, in which a temperature of constituent elements is ramped at a rate of 30° C./min or higher during the heating process.
