Abstract
Provided is a phosphor having superior light-emitting properties. A phosphor composition includes: a nitride phosphor that contains, in a composition thereof, an element M that is at least one selected from the group consisting of rare earth elements except cerium, silicon, nitrogen, and cerium; and an oxyfluoride. In the phosphor composition, a content of the oxyfluoride relative to the phosphor composition is 1.5% by mass or higher and 10% by mass or lower according to an X-ray diffraction reference intensity ratio method.
