発明の名称 (英語) COMPOSITE MATERIAL HOLLOW PARTICLES AND METHOD FOR MANUFACTURING SAME, AND FLUORESCENT MATERIAL コモンズ
発明の概要(英語) Provided are composite material hollow particles in which silica hollow particles and phosphor hollow particles are compounded, and a method for manufacturing composite material hollow particles whereby it is possible to cause the phosphor particles to be supported on surfaces of silica shells of the silica hollow particles directly and at a temperature near room temperature. These composite material hollow particles are provided with silica hollow particles comprising silica shells, and zinc-containing crystal particles supported on external surfaces and/or internal surfaces of the silica shells. In this method for manufacturing composite material hollow particles, composite material hollow particles are obtained by performing a first step, a second step, and a third step in sequence. In the first step, silica hollow particles comprising silica shells having pores, a zinc-source-containing solution including a zinc source, and an alkali-containing mixture including an alkali source are prepared. In the second step, the silica hollow particles are impregnated with the zinc-source-containing solution then filtered to obtain particles. In the third step, the alkali-containing mixture and the particles obtained in the second step are mixed together and stirred.
