Abstract

original image

Vapor-sized: In a plasma-based route to multimetallic nanoparticles (NPs), vapor mixtures of organometallic compounds are dissociated in an atmospheric-pressure microplasma (see picture). The size and composition of the particles is controlled by the relative vapor concentrations of the precursors.
