Photoluminescent Carbogenic Dots

Abstract

The chemical synthesis and photoluminescence properties of either dispersed or supported carbogenic nanoparticles are described. In the first case, ionic nanoparticles are obtained by thermal oxidation of an appropriate citrate salt. In the second, carbogenic nanoparticles decorate the external surfaces of zeolite crystals and are obtained by thermal oxidation of a preexchanged zeolite host.
