摘 要：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 emis-sion spectra of BWO:Pr microcrystals showed the strong red emission （642 nm） assigned to the Pr3+ ions of 3P0→3F2 transition with blue ex-citation （484.6 nm, 3H4→3P0）.
