•Europium-doped RbLaP4O12were prepared by flux method.•It was analyzed by infrared and Raman spectroscopy, X-ray diffraction (XRD) and Luminescence spectroscopy.•The Lumenescence spectroscopy properties confirm the potentiality of this materials to produce an intense red luminescence.
Monophasic RbLaP4O12 possessing monoclinic symmetry with varied Eu3+ concentrations was synthesized by flux method. The obtained cyclotetraphosphate exhibits very small crystals and the dopant Eu3+ ions were successfully incorporated into the sites of La3+ ions of the host lattice. These compounds were characterized by infrared and Raman spectroscopy, X-ray diffraction (XRD) and luminescence spectroscopy. The spectroscopy properties confirm the potentiality of present RbLaP4O12 doped with Eu3+ ions as luminophore host materials to produce an intense red luminescence at 616 nm corresponding to 5D0 → 7F2 emission level and have significant importance in the development of emission optical systems.
