A phosphor composition comprising a composition represented by a composition of aM 3 N 2 bAlN cSi 3 N 4 as a main body of a phosphor matrix, wherein M in the composition formula is selected from the group consisting of Mg, Ca, Sr, Ba, and Zn. At least one element, and a, b, and c satisfy 0.2 ≦ a / (a + b) ≦ 0.95, 0.05 ≦ b / (b + c) ≦ 0.8, and 0.4 ≦ c / (c + a) ≦ 0.95 The light emitting device is manufactured using the fluorescent substance composition which is a numerical value to say. Accordingly, it is possible to provide a light emitting device that emits white light, which has both high color rendering and high luminous flux. |
