•Europium–doped LiCe(PO3)4 were prepared by flux method.•It was analyzed by infrared and Raman spectroscopy, and luminescence spectroscopy.•LiCe(PO3)4 doped with Eu3+ ions as luminophore host materials to produce an intense red.
Single crystals of LiCe(PO3)4 polyphosphate have been synthesized by the flux method and its structural and luminescence properties have been investigated. This compound crystallizes in the space group C2/c with unit cell dimensions a = 16.52(7) Å, b = 7.09(4) Å, c = 9.83 (4)Å, β = 126.29(4)°, Z = 8 and V = 927.84(3) Å3. The obtained polytetraphosphate exhibits very small crystals and the dopant Eu3+ ions were successfully incorporated into the sites of Ce3+ ions of the host lattice. The spectroscopy properties confirm the potentiality of present LiCe(PO3)4 doped with Eu3+ ions as luminophore host materials to produce an intense red luminescence at 628 nm corresponding to 5D0 → 7F2 emission level and have significant importance in the development of emission optical systems.
