Phosphor, Method for Producing Same, Light Emitting Device, and Image Display Device |
摘要 |
To provide a phosphor being chemically-thermally stable and having high luminous intensity if combined with LED of not exceeding 470 nm. A phosphor of the present invention includes: inorganic compound including: a crystal represented by Li1Ba2Al1Si7N12; a crystal represented by (Li, A)3(D, E)8X12; and an inorganic crystal having the same crystal structure as the crystal represented by Li1Ba2Al1Si7N12; and a solid-solution crystal thereof, which contains Li, A, D, E, and X elements (A represents at least one selected from Mg, Ca, Sr, Ba, Sc, Y and La; D represents at least one selected from Si, Ge, Sn, Ti, Zr and Hf; E represents at least one selected from B, Al, Ga and In; and X represents at least one selected from O, N and F), wherein M element (M represents at least one selected from Mn, Ce, Pr, Nd, Sm, Eu, Tb, Dy and Yb) is solid-solved into each. |
