摘要：
A chemically and thermally stable phosphor having unconventional light emitting properties and high light emitting intensity with an LED of 470 nm or less, includes an inorganic compound comprising: a crystal designated by A3(D,E)8X14, a crystal designated by Sr3Si8O4N10 or an inorganic crystal having the identical crystal structure of the Sr3Si8O4N10 crystal, which comprises A element, D element, X element, and optionally E element if necessary (A is one or more kinds selected from Li, Mg, Ca, Sr, and Ba; D is one or more kinds selected from Si, Ge, Sn, Ti, Zr, and Hf; X is one or more kinds selected from O, N, and F; and E is one or more kinds selected from B, Al, Ga, In, Sc, Y, and La.), into which M element is solid-solved (M is one or more kinds selected from Mn, Ce, Pr, Nd, Sm, Eu, Tb, Dy, and Yb.).
