VUV Spectral Properties of MBPO7 co-doped with Tm3+,Gd3+

摘要：

　　A series of phosphor of MBPO7∶Tm3+,and MBPO7∶Tm3+,Gd3+ (M=Mg,Sr,Ca) were prepared and studied.The XRD data showed Tm3+,Gd3+ didnt affects the lattice parameters.Excitation spectra exhibited high absorption in vacuum ultraviolet (VUV) region.There existed strong emission peaking at 453nm and 363nm correspond to the 1D2→3HJ (J=4,6) emission transition of Tm 3+ when excited under VUV.With the changes of cation in the samples,the excitation spectra changed greatly,and lead a great change in its emission spectra.The crystal lattice parameters affect the ratio of intensity of the peak at 454nm and 312nm.
