The blue-green phosphors of the examples can be represented by the following formula (1), and the blue-green phosphors and the light emitting device package including the same according to the embodiments minimize the lattice defects in the crystal structure according to the composition ratio of each component included in the composition formula and the choice of the contained ions It is possible to have a characteristic that the emission characteristic is excellent and the temperature stability is improved. Formula 1 A a B b O c N d C e : RE h B is at least one or more elements selected from the group consisting of Si, Ge, and Sn; C is at least one element selected from the group consisting of C, Cl, F And Br, and RE is at least one or more elements selected from the group consisting of Eu, Ce, Sm, Er, Yb, Dy, Gd, Tm and Lu, and 0 <a≤15, 0 <b≤15, 0 <c? 15, 0 <d? 20, 0 <e? 10 and 0 <h? 10. |
