PROBLEM TO BE SOLVED: To provide a novel oxynitride phosphor having good light emission characteristics and high light emission performance, in particular, an acid emitting red light suitable for industrial production while achieving both high light emission efficiency and good temperature characteristics. A nitride phosphor and a light emitting device using the phosphor are provided. An oxynitride phosphor including a luminescent center ion in an oxynitride crystal lattice, wherein the oxynitride is represented by a chemical formula M 2 Si 5-p Al p O p N 8-p It is a compound, M is at least one element selected from Mg, Ca, Sr, Ba and Zn, and p uses an oxynitride phosphor having a numerical value satisfying the formula 0 <p <1. In addition, a light emitting device is formed using the phosphor 2 including the oxynitride phosphor and the light emitting element 1 that excites the phosphor 2. [Selection] Figure 1 |
