An object of the present invention is to provide a more efficient method for producing a nitride phosphor. A process for producing a phosphor represented by the following formula [1], which comprises a step of heating a raw material, wherein a compound essentially including at least M and Al is used as the raw material. A method for producing a phosphor. M 1-w Eu w Al x Si y N z [1] (In the above formula [1], M represents a divalent metal element in which Ca or Sr is essential. In addition, x, y, and z each represent a number in the following range. 0.0001 ≦ w ≦ 0.3 0.9 ≦ x ≦ 1.2 3.6 ≦ y ≦ 4.4 6.6 ≦ z ≦ 7.4) [Selection figure] None |
