| titleOfInvention | Fluoride phosphor, light-emitting device, and method for producing fluoride phosphor |
| abstract | [Subject] To provide an A 2 SiF 6 :Mn phosphor having high fluorescence intensity and reliability, a high-brightness light-emitting device using the phosphor, and a method for producing the phosphor. [Solution] A method for producing a fluoride phosphor represented by the general formula A 2 SiF 6 : Mn (element A is an alkali metal element containing at least potassium), characterized in that the production method comprises the steps of: preparing an element A and a step of dissolving an aqueous solution of fluorine in a solvent; and a step of adding solid silica and a manganese compound of manganese other than +7 valence to the aqueous solution, the amount of the manganese compound being added in the fluoride phosphor The Mn content is in the range of 0.1 mass % or more and 1.5 mass % or less, and the fluoride phosphor is precipitated in parallel with the dissolution of silica in the aqueous solution. |
