Abstract

Abstract: Rare earth luminescent material was modified with silane coupling agent, which was further encapsulated with a layer of polystyrene (PS) through in-situ emulsion polymerization. FTIR, TG and microscopy showed that PS uniformly grafts on the surface of rare earth luminescence materials in the form of lamella. Analysis of contact angle showed that PS/rare-earth composite luminescence materials required an excellent resistance to water. Such PS coated rare earth composite luminescence materials maintained good fluorescence performance and their original luminescence centers.

Key words: polystyrene, rare earth luminescent material, coupling agent
