摘要：

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 D-5(0) -> F-7(2) emission level and have significant importance in the development of emission optical systems.
