Abstract

(Figure Presented) The diffusion of Au in Ag₂S from the inner core to the surface of Ag₂S was reported, and a new nanocomposite of core-shell Pt@Ag₂S and Au nanoparticles has been derived through this diffusion phenomenon. Ostwald ripening was observed by transmission electron microscopy during the characterization of the nanocomposite. This elucidated the mechanism of formation of semiconductor-metal heterostructures as a consequence of Au diffusion in Ag₂S nanocrystals.
