Abstract

This work investigated the effect of electric field on digestive ripening of gold particles of nanosizes during reflux heating at 130C. The effect of electric field on the evolution of the particle size and the self-assembly of the formed gold nanoparticles is also examined. Under the action of an electric field, the polydispersed gold nanoparticle with the negative charge reached the state of nearly monodispersity. The electric field caused the increase of the particle size and induced the self-assembly of the nearly monodisperse gold nanoparticles, which is observed under high electric field intensity. The nanostructure of self-assembled gold particle nanostructures is six-fold symmetry. These experimental observations reveal that digestive ripening with the current is a new way for engineering application to control the particle size of metallic nanoparticles.
