PROBLEM TO BE SOLVED: To provide a fluophor capable of emitting bright-line green emission component by ultraviolet or violet light.SOLUTION: The fluophor has a composition represented by the general formula: AELnAMOF, where ranges of 2.5≤h+i+j≤3.5, 1≤h≤3.5, 0<i≤1 and 0≤j≤1 are satisfied. AE contains at least one element selected from alkali earth metals, Ln contains at least Ce and Tb, A contains at least one element selected alkali metals, M contains at least Al or Ga. And a peak intensity of bright-line green emission by Tbis higher than the peak intensity of broad blue green emission by Ce. |
