Abstract (en)
[origin: WO2019243637A1] The invention concerns a method for synthesising core-shell nanoparticles by laser pyrolysis, said method comprising the following steps: a) simultaneously conveying a gaseous mixture (M) comprising a silicon precursor and a germanium precursor into a reaction zone (5) of a first chamber (1) of a reactor (100), b) emitting a first laser beam at said reaction zone (5) in order to cause a laser pyrolysis of said mixture, said steps making it possible to obtain nanoparticles having a core made of a silicon and germanium based alloy and a silicon shell.
