摘要: 用高温固相法合成了系列化合物RE0.06La0.94M2O6Br(M=Nb,Ta;RE=Eu,Tb,Pr,Sm),并测定了其激发和发射光谱,室温下Eu3+、Tb3+、Pr3+、Sm3+在稀土-铌(钽)复合溴氧化物中呈现特征激发谱线,但Nb和Ta的光谱特性稍有不同。

Abstract: Aseries 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.
