Abstract
Provided are a new phosphor having emission characteristics different from the conventional nitride or oxynitride phosphor, a manufacturing method, and a light-emitting device. In an embodiment, the phosphor may include inorganic substance having crystal represented by A26(D, E)51X86 including at least A, D, X (A is at least one kind of element selected from Mg, Ca, Sr, and Ba; and D is Si, and X is at least one kind of element selected from O, N, and F); and further includes, if necessary, E (E is at least one kind of element selected from B, Al, Ga, and In) wherein the crystal further includes M (M is at least one kind of element selected from Mn, Ce, Pr, Nd, Sm, Eu, Tb, Dy, and Yb). Upon irradiation of excitation source, the maximum value of emission peak in a wavelength range from 630 nm to 850 nm may occur.
