Abstract
The present application provides a method for fabricating core-shell particles, including: forming a first solution by adding a first metal salt and a first surfactant to a first solvent; forming core particles including a first metal included in the first metal salt by adding a first reducing agent to the first solution; forming a second solution by adding the core particles, a second metal salt, and a second surfactant to a second solvent; and forming core-shell particles by adding a second reducing agent to the second solution and forming shells on the surface of the core particle, in which the first surfactant and the second surfactant are polyoxyethylene, polyoxyethylene sorbitan monolaurate or polyoxyethylene oleyl ether, and core-shell particles fabricated by the method.
