WAVELENGTH CONVERSION PARTICLE, METHOD FOR PRODUCING SAME, WAVELENGTH CONVERSION MEMBER, AND LIGHT-EMITTING DEVICE

摘要

The present invention pertains to: a wavelength conversion particle provided with a fluorescent body particle, which contains an alkaline earth metal, and a coating film that covers the surface of the fluorescent body particle, has at least one selected from the group consisting of an alkaline earth metal sulfate, borate, and titanate as the primary component, and has a lower refractive index than the fluorescent body particle; a method for producing the wavelength conversion particle; a wavelength conversion member having the wavelength conversion particle; and a light-emitting device having the wavelength conversion member. As a result of providing the coating film, it is possible to increase conversion efficiency and moisture resistance.
