Preparation of silver nanoparticles in soda-lime silica glass by an electrochemical procedure

► An electrochemical procedure for obtaining silver nanoparticles in glasses is presented. ► The cell used allow only the migration of Ag ions through the glass as electrolyte. ► Ag particles are formed by a redox reaction involving Fe ions. ► Particles of average size between 2 nm to 6 nm are obtained.
