摘要：

The fluorescence spectrum of La1-xPrxP5O14 was investigated for the range of 0.001 ≤ x ≤ 1. For small Pr3+-concentration the fluorescence starts almost completely from the 1D2 level, whereas in pure PrUP the total fluorescence arises from the energetically higher 3P0 level. This is contrary to the usually observed concentration quenching. In the intermediate concentration range fluorescence lines from both levels are observed independent of the excitation. © 1979.
