PROBLEM TO BE SOLVED: To provide a phosphor that is efficiently excited by ultraviolet rays or visible light and emits red light, and a light emitting device using the same. The phosphor is represented by a general formula Eu 2-x Ln x M 3 O 12 . However, 0 ≦ x <2, Ln in the composition is at least one selected from Y, La and Gd, and M is at least one selected from the group consisting of W or Mo. A combination of the phosphor and a light emitting element such as a nitride semiconductor light emitting element can be used as a light emitting device. [Selection figure] None |
