METHOD FOR CONTROLLING THE FORMATION OF METALLIC NANOPARTICLES IN GLASS AND PRODUCTS THEREOF

摘要

A method of forming metallic nanoparticles in glass is disclosed that creates evenly distributed metallic nanoparticles with desired size in any glass type.;Formation of a source of electrons trapped on the surface of the glass particles by crushing and grinding glass material into powder followed by heat treatment of the glass powder to neutralise metal ions doped in the glass by the trapped source of electrons, followed by the aggregation and growth of the metal into nanoparticles. The present method allows the homogeneous distribution of metal nanoparticles throughout the glass volume. The size and concentration of the metallic nanoparticles is controlled by the heat treatment temperature and duration as well as the amount of metal ions.
