Abstract

The energy migration processes in EuTa₇O₁₉, TbTa₇O₁₉ and La_0.86Tm0.14Ta₇O₁₉ are reported. The decay characteristics of the Eu³⁺ and Tb³⁺ emission can be explained by using a quasi-two-dimensional migration model, not by a two-dimensional migration model. In contrast, the characteristics of the Tm³⁺ emission can be explained by using the cross-relaxation energy transfer model.
