The phosphor of ScPO4:Zr^<4+>,Mn^<2+> has been synthesized in order to increase the photoluminescence (PL) intensity of the blue-green (BG) band at 2.52 eV in YPO_4: Zr^<4+>,Mn^<2+> phosphor. PL properties of this material have been investigated. A PL band is predominantly observed at 2.34 eV in ScPO_4:Zr^<4+>,Mn^<2+>. This green (G) band is most likely caused by the intra-3d transition of the Mn^<2+> ion occupying a Sc^<3+> site, in analogy with PL properties of the BG band. The G band surpasses the BG band in PL intensity. Discussions are conducted on the change of PL properties in ScPO_4:Zr^<4+>,Mn^<2+> phosphor.
