<p>The present invention relates to a novel green fluorescent body and a light-emitting diode device including the same and, more specifically, to a fluorescent body represented by Chemical Formula 1. The fluorescent body of the present invention has a wider half width than the wavelength of existing garnet oxides. [Chemical Formula 1] (Lu_1_(-(x1+x2)),R_(x1),A_(x2))_3(Al_((1-y)),B_y)_5(O_((1-z)),C_z)_(12) Herein, A is one selected from the group consisting of bivalent or trivalent cationic metal elements such as Y, Gd, Sm, Tb, La, Sr, Ba, and Ca; B is one selected from the group consisting of Family IV elements such as C, Si, Ge, Sn, and Pb or from B and Ga; C is one selected from the group consisting of anions such as F, Cl, Br, N, and S; R is Ce; 0<X1+X2<1; 0<Y<1; and 0<Z<1.</p> |
