摘要
Embodiments of the present invention provide a bluish green phosphor represented by Formula 1 below. In particular, the bluish green phosphor and a light emitting device package including the same may have improved luminescence characteristics and properties due to influence of cations and anions included in a composition formula: €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ[Formula 1]€ƒ€ƒ€ƒ€ƒ€ƒA a B b O c N d C e D f E g :RE h wherein A is at least one selected from the group consisting of Be, Mg, Ca, Sr, Ba and Ra elements, B is at least one selected from the group consisting of Si, Ge and Sn elements, C is any one of C, Cl, F and Br elements, D is one element or a mixture type of two or more elements selected from Li, Na and K, E is at least one selected from the group consisting of P, As, Bi, Sc, Y and Lu, RE is at least one selected from the group consisting of Eu, Ce, Sm, Er, Yb, Dy, Gd, Tm, Lu, Pr, Nd, Pm and Ho, 0a‰¤15, 0b‰¤15, 0c‰¤15, 0d‰¤20, 0e‰¤10, 0f‰¤6, 0g‰¤6, and 0h‰¤10.
