METHOD FOR FORMING FILM OF SULFIDE-BASED PHOSPHOR AND SURFACE-COATED SULFIDE-BASED PHOSPHOR

摘要

PROBLEM TO BE SOLVED: To provide a method for forming a film of a sulfide-based phosphor and a surface-coated sulfide-based phosphor. SOLUTION: The method for forming a film of a sulfide-based phosphor contains a step to prepare sulfide-based phosphor powder, a step to form an organic polymer coating film containing silicon on the surface of the phosphor powder particle by applying a silane modifying agent to the sulfide-based phosphor powder and a step to carry out the heat-treatment of the sulfide-based phosphor powder to form a silicon oxide film from the organic polymer film.
