Abstract Sr 2 P 2 O 7 :Eu 2+ /Eu 2+ ,Mn 2+ phosphors have been synthesized by the facile and mild precipitation method and they are characterized by X-ray powder diffraction, scanning electron microscopy, photoluminescence spectra. The SEM results indicate the obtained Sr 2 P 2 O 7 :Eu 2+ phosphors have the columnar structure and the Sr 2 P 2 O 7 :Eu 2+ ,Mn 2+ phosphors is the sphere like. The effects of the stirring and sintering temperature on the morphology of Sr 2 P 2 O 7 :Eu 2+ /Eu 2+ ,Mn 2+ phosphors have been investigated. The photoluminescence spectra of Sr 2 P 2 O 7 :Eu 2+ and Sr 2 P 2 O 7 :Eu 2+ ,Mn 2+ phosphors showed that the Sr 2 P 2 O 7 :Eu 2+ phosphors can be excited by 345 nm and exhibit blue emission around 421 nm and the Sr 2 P 2 O 7 :Eu 2+ ,Mn 2+ phosphors can be excited by 355 nm and exhibited the emission around 420 nm and 578 nm showing the white light.
