Abstract
Provided is a method for manufacturing metal nanoparticles having a core-shell structure with good oxidation stability, wherein the method comprises the steps of: heating and agitating a core metal precursor solution; mixing a shell metal precursor solution with the heated and agitated core metal precursor solution, and heating and agitating the mixed metal precursor solution; and irradiating the heated and agitated metal precursor solution with radioactive rays. Thus, since yield can be maximized through a simple and environmentally friendly process that does not use a chemical reducing agent, there is no need for a process for removing an added reducing agent, and since a post-heat-treatment of particles is not performed, the manufacturing process is rendered simple and highly economical.
