発明の名称 (英語) PHOSPHATE PHOSPHOR AND METHOD FOR MANUFACTURING PHOSPHATE PHOSPHOR
発明の概要(英語) [Problem] To provide a phosphate phosphor consisting of a novel oxide that emits red light. [Solution] This phosphate phosphor is characterized in that: said phosphate phosphor contains NaMgPO4 activated by light-emitting ions including europium; the activation concentration of said light-emitting ions is between 1 and 10 mol.%, inclusive; the NaMgPO4 exhibits an olivine-like crystal structure; and this phosphate phosphor emits light of an orange to red color. To make this phosphate phosphor emit light of a somewhat deep red color, some of the phosphorus should be replaced by silicon and/or aluminum. In a firing step for manufacturing such phosphate phosphors, a mixture of starting materials is preferably cooled after being melted.
