英文摘要 | This work provides a scheme to investigate the site occupancy and the luminescence properties of lanthanide ions in bay2si3o10. the rietveld refinement of the samples indicates that the lanthanide ions preferably occupy the y3+ sites in bay2si3o10. it is confirmed that valence state of lanthanide ions is stable at +3 in all doping samples. the site dependent spectroscopic properties of ce3+ and eu3+ are studied in vuv-uv-vis spectral region at low temperatures, and the polarization effect on ce3+ luminescence decay is evaluated. the results indicate that the lanthanide ions experience the similar polarization effect when substituting the y3+ sites in bay2si3o10. the stokes shift of ce3+ luminescence becomes larger as ce3+ doping content increases. eu3+ f-f line-shape change has not been observed in the spectra as eu3+ content increases. it demonstrates that the change of the electrostatic binding effect in the lattice has little effect on the ligand polarization of the central lanthanide ion. finally, a mechanism is proposed to explain why the thermal-quenching of ce3+ luminescence is negligible in bay2si3o10 even if the temperature increases up to 500 k. the influence of dynamic ion lattice interaction on luminescence properties of the lanthanide ions in bay2si3o10 is discussed in detail. |
