The energy migration processes in EuTa7O19, TbTa7O19 and La0.86Tm0.14Ta7O19 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.
