Method and device for producing nanoparticles by laser irradiation microscopic liquid precursors

摘要

The present invention is to provide a device and method of producing nanoparticles free of contamination by particles larger than permitted, but not limited to, the use of laser sources nanoseconds under atmospheric pressure. The process for the production of nanoparticles by laser ablation comprises using as a precursor a liquid solution dropwise microscopic comprising a solution of the precursors of the nanoparticles. This procedure: increases the reproducibility of the laser-field coupling, prevents the generation of aerosols created in the precursor and results in a free adiabatic expansion condensation liquid phase.
