Abstract

Provided is a wavelength converting member and a method of producing the same. Proposed is a wavelength converting member including: a fluorescent material containing at least one kind selected from a nitride-based fluorescent material and an oxynitride-based fluorescent material; and an aluminate containing at least one kind selected from the group consisting of a rare earth aluminate and an alkaline earth metal aluminate. Further, a method of producing a wavelength converting member, including: preparing a molded body obtained by mixing a fluorescent material containing at least one kind selected from a nitride-based fluorescent material and an oxynitride-based fluorescent material and an aluminate containing at least one kind selected from the group consisting of a rare earth aluminate and an alkaline earth metal aluminate; and sintering the molded body to obtain a wavelength converting member containing the fluorescent material and the aluminate, is proposed.
