Document Type and Number:
WIPO Patent Application WO/2022/107794
Kind Code:
A1
Abstract:
The present invention provides a manufacturing method for a wavelength conversion member, the method making it possible to accurately obtain a wavelength conversion member with a desired chromaticity. Provided is a manufacturing method for a wavelength conversion member 1 in which phosphor particles 3 are dispersed in a matrix 2. The manufacturing method for the wavelength conversion member 1 comprises: a step for producing a mixture including inorganic powder that becomes the matrix 2, and the phosphor particles 3; and a step for obtaining the wavelength conversion member 1 by molding and firing the mixture, wherein, in the production of the mixture, after the start of mixing of a material containing the inorganic powder, the phosphor particles 3 are put in and mixed.
