Abstract: The present invention relates to a method for synthesizing metal or metal oxide nanoparticles by liquid-phase deposition on a surface layer of a substrate, comprising the following successive steps:—a step of thermally pretreating the conductor or semiconductor surface layer of a substrate, comprising the application of a specified temperature;—a step of impregnating the pretreated surface layer of the substrate with an organometallic complex in solution in an aprotic solvent;—a step of annealing under controlled atmosphere, and wherein the specified temperature is selected to obtain a predefined size of nanoparticles between 4 and 60 nm with a dispersion less than or equal to 30%. The invention is adapted to applications of nanoparticles in the field of microelectronics, optics or catalysis.
