摘要：

The Nasicon-type phosphate CuZr2(PO4)3 exhibits two fluorescences occurring in the violet and green regions. They are assigned to two different centres: the violet one to isolated Cu+ and the green one to Cu+ -Cu+ pairs occupying the same site. These assignments are in agreement with previous structural investigations using x-ray, neutron and EXAFS measurements and provide information about the location of copper ions in the crystal. A third luminescence is detected in the blue range at low temperature. The origin of this fast, strong emission is not clearly established. It could be due to Cu+ -Cu0 pairs in the M(1) site.
