In this project, metal-metal oxide yolk-shell nanoparticles embedded in host film will be fabricated by the modified pulsed laser deposition method and in situ thermal oxidation technique. The formation mechanism of metal-metal oxide yolk-shell nanoparticles will be systematically investigated. The optical, electrical and magnetic properties of the metal-metal oxide yolk-shell nanoparticles will be controlled by optimization of the shell thickness, the core size and the void spaces of the yolk-shell nanoparticles. The purpose of this project is to fabricate monodispersed metal-metal oxide yolk-shell nanoparticles film with controllable properties and uniform morphology. The novel microstructure and properties of the metal-metal oxide yolk-shell nanoparticles film can be therefore achieved.
