titleOfInvention | Method for producing nitride fluorescent material, and nitride fluorescent material |
abstract | A method for producing a nitride fluorescent material includes preparing fluorescent material core particles having a composition containing Sr, Ca, Eu, Al, Si, and N, in which, when a molar ratio of Al in the composition is 1, a molar ratio of Sr is in a range of 0.45 or more and 1.1 or less, a molar ratio of Ca is in a range of more than 0 and less than 0.55, a molar ratio of Eu is in a range of more than 0 and 0.033 or less, a total molar ratio of Sr, Ca, and Eu is 1.1 or less, a molar ratio of Si is in a range of 0.81 or more and 1.21 or less, and a molar ratio of N is in a range of 2.25 or more and 3.85 or less, subjecting them to a first heat treatment and a second heat treatment. |
