Document Type and Number:
Japanese Patent JP6700630
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a phosphor which has a high light emission intensity even in combination with an LED of 470 nm or less, and is chemically and thermally stable.SOLUTION: The phosphor according to the present invention comprises either: an inorganic crystal containing a metallic element M and a nonmetallic element X and represented by MX(n being a numerical value in the range of 3≤n≤52); an inorganic crystal having the same crystalline structure; or an inorganic compound that is a solid solution, in an inorganic crystal being a solid solution of them, of an element A (A being one or more elements selected from among Mn, Ce, Pr, Nd, Sm, Eu, Tb, Dy and Yb). Here, M comprises at least Al, Si and an optional element L (the element L being a metallic element other than Al and Si), and X comprises at least N, optional O, and an optional element Z (the element Z being a nonmetallic element other than N and O).SELECTED DRAWING: Figure 1
