Document Type and Number:
Japanese Patent JP6083881
Kind Code:
B2
Abstract:
A phosphor having different light emission characteristics from the conventional phophor, having high emission intensity and chemial and thermal stability, combined with LED of less than 450 nm. This phosphor includes an inorganic compound comprising: a crystal represented by Ba 1 Si 4 Al 3 N 9 , an inorganic crystal having the same crystal structure as Ba 1 Si 4 Al 3 N 9 crystal, or a solid solution crystal thereof, comprising A element, D element, E element, and X element (A is one or more elements selected from Li, Mg, Ca, Sr, Ba, and La; D is one or more elements selected from Si, Ge, Sn, Ti, Zr, and Hf; E is one or more elements selected from B, Al, Ga, In, Sc, and Y; X is one or more elements selected from O, N, and F), into which M element is solid-solved (M is one or more elements selected from Mn, Ce, Pr, Nd, Sm, Eu, Tb, Dy, and Yb).
