摘要

化合物EuAl3B4O12表现出5D0激发能级间的热活化能迁移。在NaEuTiO4中，这种迁移减少到二维，直到最低温度，而在euumgb5o10中则观察到一维迁移。在短距离和低温下，Eu3+-Eu3+通过交换发生转移。

ENERGY MIGRATION IN EU3+ COMPOUNDS ; ITS DEPENDENCE ON DIMENSIONALITY AND EU3+-EU3+ DISTANCE

The compound EuAl3B4O12 shows thermally activated energy migration among the 5D0 excited level. In NaEuTiO4 this migration reduces to two-dimensional, down to the lowest temperatures, whereas in EuMgB5O10 one-dimensional migration is observed. For short distances and low temperatures the Eu3+-Eu3+ transfer occurs by exchange.
