phosphors were synthesized by a solid-state reaction method. The phase of the as-prepared samples were measured by X-ray diffraction pattern (XRD)

and the results showed that the samples were pure phase. The exciation spectrum includes a series of wide bands and the peaks which locate at 322

was investigated

the concentration quenching occurred when
