BaWO4:Pr3+ (hereafter BWO:Pr) microcrystals were prepared via a hydrothermal route,and characterized by X-ray diffraction (XRD),scanning electron microscope (SEM),photoluminescence excitation and emission spectra.The as-prepared products with different morphologies of egg-shape rod,olive-like,and quasi-sphere were obtained by the addition of the surfactants and chelating agents.The emission spectra of BWO:Pr microcrystals showed the strong red emission (642 nm) assigned to the Pr3+ ions of 3p0→3F2 transition with blue excitation (484.6 nm,3H4→3p0).
