Abstract
Spherical MWO4:Tb3+ (M = Ca, Sr, Ba) particles were synthesized by a hydrothermal route at 180 °C for 10 h. The synthesized MWO4:Tb3+ particles were characterized by X-ray powder diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), and luminescence spectroscopy. The XRD and FT-IR results show that MWO4:Tb3+ particles with a scheelite-type crystal structure were synthesized successfully. The SEM and TEM results show that uniform spherical particles in the range of hundreds of nanometers were obtained. The possible growth mechanism may be attributed to a typical Ostwald ripening process. The excitation spectra of MWO4:Tb3+ phosphors show a strong absorption band of the WO4 2− group and some weak absorption bands of Tb3+ ions. The emission spectra of MWO4:Tb3+ phosphors show the characteristic emission bands of Tb3+ ions. CaWO4:Tb3+ sample has the highest excitation and emission intensity.
