Cu@Ag core-shell nanoparticle with multiple morphologies: A simple surfactant-free synthesis and finite element simulation

Abstract

Cu@Ag nanoparticles with multiple morphologies were prepared using the galvanic exchange method with surfactant-free in air. The thermal stability of as-prepared nanoparticles was evaluated by thermo-gravimetric analysis and the morphology evolution of the sample as conductive ink was investigated by using a scanning electron microscope. In the meantime, the optical properties of synthesised nanoparticles were simulated by the finite-element method. It is feasible for Cu@Ag nanoparticles to be applied as a conductive.
