| Abstract: The Tb3+-doped CaSr(WO4)2, SrBa(WO4)2 and (Ca1-xBax)WO4 have been synthesized.The emission and excitation spectra were measured. The crystal structures were studied by means of powder X-ray diffraction and single crystal electron diffraction methods.The compositions of (Ca1-xBax)WO4 were analyzed with X-ray energy dispersive spectromcter(EDS).The miscibility of alkali-earth metal tungstates,and the luminescence of Tb3+ion and energy transfer mechanism were discussed. |
| Keywords: alkali-earth metal tungstate miscibility luminescence |
