Abstract

La presente invención es proporcionar un dispositivo y procedimiento de producción de nanopartículas libres de contaminación por partículas de tamaño superior que permite, pero no limita a, el uso de fuentes láser de nanosegundos bajo presión atmosférica. El procedimiento para la producción de nanopartículas mediante ablación con láser caracterizado porque se emplea como precursor una solución líquida en forma de gota de tamaño microscópico que comprende una disolución de los precursores de las nanopartículas. Este procedimiento: aumenta la reproducibilidad del acoplamiento láser-materia, impide la generación de aerosoles que se originan en el precursor y da lugar a una expansión adiabática libre de condensación de fase líquida.The present invention is to provide a device and method for producing nanoparticles free from contamination by particles of larger size that allows, but does not limit, the use of nanosecond laser sources under atmospheric pressure. The process for the production of nanoparticles by laser ablation characterized in that a liquid solution in the form of a microscopic-sized droplet comprising a solution of the precursors of the nanoparticles is used as a precursor. This procedure: increases the reproducibility of the laser-matter coupling, prevents the generation of aerosols originating in the precursor and results in an adiabatic expansion free of liquid phase condensation.
