摘要： A light-emitting device 1 according to the present invention includes: a solid-state light-emitting element 10 that radiates laser light; and a wavelength converter 50 including plural types of phosphors which receive the laser light and radiate light. The phosphors included in the wavelength converter 50 are substantially composed of Ce3+-activated phosphors. The above-described light-emitting device includes at least a warm-color Ce3+-activated phosphor that receives the laser light and radiates light having a light emission peak within a wavelength range of 580 nm or more to less than 660 nm, and light-emitting components radiated by the phosphors are composed of only light-emitting components derived from Ce3+.

摘要： 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.
