Abstract
The diffusion of Au in Ag(2)S from the inner core to the surface of Ag(2)S was reported, and a new nanocomposite of core-shell Pt@Ag(2)S 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 Ag(2)S nanocrystals.Entities:
