Document Type and Number:
Japanese Patent JP5920773
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a phosphor that has a high emission intensity and is chemically and thermally stable when combined with an LED having ≤470 nm.SOLUTION: A phosphor comprises an inorganic compound which contains elements of A, D, E and X (A is at least one element selected from Mg, Ca, Sr and Ba, D is at least one element selected from Si, Ge, Sn, Ti, Zr and Hf, E is at least one element selected from Al, Ga, In, Sc, Y and La an X is at least one element selected from O, N and F) and in which M (M is at least one element of Mn, Ce, Pr, Nd, Sm, Eu, Tb, Dy, Yb) forms a solid solution in any crystal of an N crystal containing a structure of AB(D, E)X, a structure of A(D, E)Xor a structure of (1-x)AB(D, E)X+xA(D, E)X(0≤x≤1), an inorganic crystal having the same crystal structure as the N crystal and a solid solution crystal of these crystals.
