Provided is a method for manufacturing MAl2O4:Eu,RE type long-lasting phosphor ceramics capable of producing the ceramics at a reduced raw material cost. In addition, provided is a sintered product of a long-lasting phosphor having no yellow body color. More specifically, provided are the method for manufacturing MAl2O4:Eu,RE type long-lasting phosphor ceramics in which M is an alkaline earth element and RE is a rare earth element other than europium, comprising mixing a BAM (alkaline earth aluminate) phosphor, an alkaline earth compound, an aluminum compound and a rare earth compound to form a mixture, and then firing the mixture; and a white MAl2O4:Eu,RE type long-lasting phosphor. |
