| Abstract: | A series of compounds,REO0.06La0.94M2O6Br(M=Nb,Ta;RE=Eu,Tb,Pr, Sm),have been synthesized by solid reaction method at high temperature,and their excitation and emission spectra have been measured. The Eu3+, Tb3+,Pr3+ and Sm3+in La-Nb(Ta)complex bromoxide showed the characteristic excitation and emission lines at room temperature.However,the spectral properties at Nb compounds are lightly different from that Ta compounds. |
