The present invention provides a phosphor, which has high luminous intensity when combined with an LED with a wavelength of 470 nm or less, and has good chemical stability and thermal stability. The phosphor of the present invention contains Li element, A element, D element, E element, X element (A is at least one element selected from Mg, Ca, Sr, Ba, Sc, Y, La; D is selected from Si , Ge, Sn, Ti, Zr, Hf at least one element; E is at least one element selected from B, Al, Ga, In; X is at least one element selected from O, N, F) by A crystal represented by Li 1 Ba 2 Al 1 Si 7 N 12 , a crystal represented by (Li,A) 3 (D, E) 8 X 12 , and a crystal represented by Li 1 Ba 2 Al 1 Si 7 N 12 An inorganic compound in which M element (where M is at least one element selected from Mn, Ce, Pr, Nd, Sm, Eu, Tb, Dy, and Yb) is solid-dissolved in inorganic crystals with the same crystal structure. |
