| titleOfInvention | Manufacturing method of nitride phosphor and nitride phosphor |
| abstract | The present invention provides a method for producing a nitride phosphor having excellent durability and a nitride phosphor. A method of manufacturing a nitride phosphor, comprising the step of preparing phosphor core particles having a composition including Sr, Ca, Eu, Al, Si, and N, and adding Al in the composition When the molar ratio of Sr is set to 1, the molar ratio of Sr is in the range of 0.45 or more and 1.1 or less, the molar ratio of Ca is in the range of more than 0 and less than 0.55, and the molar ratio of Eu is in the range of more than 0 and 0.033 or less. , the total molar ratio of Sr, Ca and Eu is 1.1 or less, the molar ratio of Si is in the range of 0.81 or more and 1.21 or less, and the molar ratio of N is in the range of 2.25 or more and 3.85 or less; A step of performing a first heat treatment at a temperature in the range of 70° C. or higher and 150° C. or lower in contact with the phosphor core particles; A temperature within the range of the second heat treatment step is performed. |
