<p>A method for preparing a phosphor that comprises a crystalline oxide having M 1 O 3 (M 1 is a tetravalent metallic element) as a main backbone thereof and essentially including a halogen element X (X is at least one element selected from a group consisting of F, Cl, Br, and I) and divalent metal ions M 2 and Eu 2+ , includes using a compound represented by a compositional formula NH 4 X as a starting material when synthesizing the phosphor. At least a compound represented by a compositional formula NH 4 Cl may be used as the starting material.</p> |
