| 论文摘要 | The 0.8CaWO(4)-0.2EuMO(4) (M = Nb, Ta) solid solution and Eu3+, Ta5+ and Nb5+ single doped CaWO4 were prepared by a high-temperature solid state reaction technique. Experiments show that the addition of Nb5+ and Ta5+ can increase the red luminescence of Eu3+ in CaWO4. In this paper, the composition and structure of solid solution were analyzed by X ray diffraction (XRD), Fourier transform infrared spectrum and Raman spectrum analysis. The luminescence properties of the solid solution were studied by means of stable photoluminescent spectra, diffuse reflectance spectra (DRS), fluorescent decay curves and variable temperature spectra. By combining structural analysis, J-O theoretical calculation and experimental results, we believe that the significant improvement of the emission efficiency comes from the decrease of non-radiation relaxation rate. |
