Abstract:
Provided is a chemically and thermally stable phosphor having different light-emitting characteristics than a conventional phosphor and having high light-emitting intensity even when combined with an LED of 410 nm or lower. The phosphor comprises an inorganic compound in which an inorganic crystal including A element, D element, X element (A is one or more elements selected from Mg, Ca, Sr, and Ba; D is one or more elements selected from Si, Ge, Sn, Ti, Zr, and Hf; and X is one or more elements selected from O, N, and F), and, if necessary, E element (where E is one or more elements selected from B, Al, Ga, In, Sc, Y, and La) includes Li element and M element (where M is one or more elements selected from Mn, Ce, Pr, Nd, Sm, Eu, Tb, Dy, and Yb).
