Abstract: Provided is a wavelength converter including a phosphor ceramic containing a first phosphor that emits fluorescence due to a parity-forbidden transition, and a phosphor part containing a second phosphor that emits fluorescence due to a parity-allowed transition. A main surface of the phosphor ceramic has a concave and convex structure including a plurality of convex parts and a plurality of concave parts. The phosphor part is arranged inside the plurality of concave parts in the phosphor ceramic. Also provided is a light emitting device including the wavelength converter, and a solid-state light source that emits light with which the wavelength converter is irradiated and which has a light emission peak within a wavelength range of 400 nm or more and less than 500 nm.

Abstract: A method of manufacturing a surface-treated phosphor (11) in which the surface of an alkaline-earth silicate phosphor (12) containing a silicate of alkaline-earth metal is covered with a surface treatment layer (13), the method comprising: surface treatment which brings the alkaline-earth silicate phosphor (12) into contact with the surface treatment substance (23) molten or pyrolyzed to form the surface treatment layer (13) on the surface of the alkaline-earth silicate phosphor (12) wherein the surface treatment substance (23) is at least one selected from a group consisting of a sulfate, a phosphate, a carbonate, a borate, a boric acid, a titanate, and a fluoride.

Abstract: A fond de veau is produced by boiling baked meats for extraction independently, separating a boiled extract therefrom, and reacting a protease with at least a residue of the meats to produce a protein decomposition solution, and then using said protein decomposition solution and said boiled extract separated from the baked meats boiled; or a protein hydrolytic solution obtained by reacting a protease on baked meats without boiling, with a boiled extract of fried vegetables. There is provided a process for easily producing a fond de veau in an industrial manner that has a quality equivalent to a fond de veau produced by a professional culinarian in a high yield.
