Provided is method for synthesising core-shell nanoparticles by laser pyrolysis. The method may include a) conveying together a gaseous mixture including a silicon precursor and a germanium precursor in a reaction zone of a first chamber of a reactor, and b) emitting a first laser beam at the level of the reaction zone for carrying out a laser pyrolysis of the mixture, the steps making it possible to obtain nanoparticles having a core made of a silicon- and germanium-based alloy and a silicon shell.

Some embodiments are directed to a multimaterial powder used in the field of metallurgy and plasturgy. The multimaterial powder includes support particles having a median particle size distribution between 1 μm and 100 μm and functionalising particles having a median particle size distribution that is a factor of 10 to 1000 lower relative to the support particles. The powder is characterised in that the support particles and the functionalising particles form composite grains having a core-shell structure that each have a core formed by a support particle, and a shell, that covers between 10 and 100% of the surface of the support particle and which is formed by at least one surface layer of the functionalising particles.
