摘要：

The phosphor of ScPO4: Zr4+, Mn2+ has been synthesized in order to increase the photoluminescence (PL) intensity of the blue-green (BG) band at 2.52 eV in YPO4: Zr4+,Mn2+ phosphor. PL properties of this material have been investigated. A PL band is predominantly observed at 2.34 eV in ScPO4:Zr4+, Mn2+. This green (G) band is most likely caused by the intra-3d transition of the Mn2+ ion occupying a Sc3+ 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 ScPO4:Zr4+, Mn2+ phosphor.
