Title:
FLUORESCENT MEMBER, METHOD FOR PRODUCING SAME, AND LIGHT-EMITTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/015261
Kind Code:
A1
Abstract:
This fluorescent member is a sintered body for wavelength conversion, which contains: a matrix comprising magnesium oxide and magnesium hydroxide as primary components; and fluorescent particles dispersed in the matrix. The thermal conductivity of the fluorescent member is preferably 5 W/(m·K) or more. Provided are: a fluorescent member that exhibits both thermal conductivity and fluorescence without the need for a high temperature firing process (a high temperature process in which the temperature exceeds 250°C); a method for producing same; and a light-emitting device.
