Abstract:
A production method of a phosphor includes firing a starting material mixture in a nitrogen atmosphere at a temperature range between 1,500° C. inclusive and 2,200° C. inclusive. The starting material mixture is a mixture of metallic compounds, and is capable of constituting a composition including M, A, Al, O, and N (M is Eu; and A is one kind or two or more kinds of element(s) selected from C, Si, Ge, Sn, B, Ga, In, Mg, Ca, Sr, Ba, Sc, Y, La, Gd, Lu, Ti, Zr, Hf, Ta, and W) by firing.
