  • Patent number: 10968387
    Abstract: A phosphor, combined with LED having not exceeding 470 nm, of high emission intensity and with chemical and thermal stability is provided. The phosphor according to the present invention comprises an inorganic compound in which element A (A is one or two or more kinds of elements selected from Mn, Ce, Pr, Nd, Sm, Eu, Tb, Dy, and Yb) is solid solved in an inorganic crystal including at least metal element M and non-metal element X and represented by MnXn+1 (3?n?52), an inorganic crystal having the same crystal structure, or an inorganic crystal including a solid solution thereof. Here, M comprises at least Al and Si, and if necessary element L (L is a metal element other than Al and Si) and X comprises N, O if necessary, and element Z if necessary (Z is a non-metal element other than N and O).
