Abstract

A novel orange SrMoO4:Pr3+, B3+, Li+ phosphor is prepared via the high-temperature solid state reaction process, and its structure, morphology and luminescence properties are studied. The X-ray diffraction (XRD) patterns show that a pure SrMoO4 crytal phase is obtained at 1200 ℃. The morphology of the sample under scanning electron microscope (SEM) has good dispersity and irregular shapes. The excitation spectra are made up of charge transfer band and characteristic transitions of 3H4→3P2,1,0 (448, 473, 487 nm, respectively) of Pr3+. The emission spectra of the SrMoO4:Pr3+, B3+, Li+ phosphors are characterized by peaks at 529(3P1→3H4,5), 545(3P0→3H5), 553(3P0→3H5), 600(1D2→3H4), 617(3P0→3H6), 645 nm (3P0→3F2). The strongest one appears at 645 nm. The intensity of excitation and emission peaks of SrMoO4:Pr3+ can be improved by doping B3+ and Li+. The optimum doping mole fractions are 0.15% B3+ and 0.35% Li+, respectively.
