Phosphors having high light emission luminescence |
摘要 |
Provided are phosphors that can exhibit higher emission luminance. Phosphors in which the activator is included in a compound represented by Formula xM1O.M2O.yM3O2 (wherein M1 represents one or more of a group comprising Ca, Sr and Ba, M2 represents Mg and/or Zn, M3 represents Si and/or Ge, x is a value in the range 4 to 6 and y is a value in the range 2 to 4). Phosphors represented by Formula M15(1−z)EuzM2M33O12 (wherein M1, M2 and M3 have the same meanings as above, and z is a value in the range 0.0001 to 0.3). The above phosphors have the same crystal structure as bredigite.
