Abstract

$SrMoO_4:RE^{3+}$ (RE = Eu or Tb) phosphors were synthesized with different concentrations of activator ions by using the conventional solid-state reaction method. The effects of the concentration of activator ions on the structural, morphological, and optical properties of strontium molybdate phosphors were investigated by using X-ray diffraction, scanning electron microscopy, and fluorescence spectrophotometry, respectively. XRD patterns revealed that all synthesized phosphors showed the tetragonal $SrMoO_4$ structure, irrespective of the type and the concentration of activator ions. The crystallite size showed an overall increasing tendency with increasing concentration of activator ions. The emission spectra of $Eu^{3+}$-doped $SrMoO_4$ phosphors under excitation at 295 nm exhibited one intense red band at 619 nm and five weak bands centered at 541, 561, 596, 657, and 704 nm, respectively. For the $Tb^{3+}$-doped $SrMoO_4$ phosphors, a strong emission peak at 550 nm and two weak lines, 494 and 591 nm, were observed. The intensities of all the emission bands reached maxima when 0.05 mol of $Tb^{3+}$ ions was used. The results suggest that the optimum concentrations for synthesizing highly-luminescent red and green phosphors are 0.01 mol and 0.05 mol, respectively.
