ABSTRACT
Monophasic RbLaP4O12 possessing monoclinic symmetry with varied Eu(3+) concentrations was synthesized by flux method. The obtained cyclotetraphosphate exhibits very small crystals and the dopant Eu(3+) ions were successfully incorporated into the sites of La(3+) 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 Eu(3+) ions as luminophore host materials to produce an intense red luminescence at 616 nm corresponding to (5)D0â(7)F2 emission level and have significant importance in the development of emission optical systems.
