Laser assisted embedding of nanoparticles into metallic materials

This paper reports a methodology of half-embedding nanoparticles into metallic materials. Transparent and opaque nanoparticles are chosen to demonstrate the process of laser assisted nanoparticle embedding. Dip coating method is used to coat transparent or opaque nanoparticle on the surface of metallic material. Nanoparticles are embedded into substrate by laser irradiation. In this study, the mechanism and process of nanoparticle embedding are investigated. It is found both transparent and opaque nanoparticles embedding are with high densities and good uniformities.

► Half-embedding nanoparticles with diameter less than 100 nm into metallic materials. ► Large area and uniform distribution of half-embedded nanoparticles are achieved using a pulsed laser irradiation to induce substrate melting. ► This process works for both transparent and opaque nanoparticles ► Various types of surface properties of metallic materials can be introduced by these half-embedded nanoparticles.
