摘要：

The distribution of Ce in orthophosphate Sr-3(PO4)(2) was investigated by the combined single-crystal X-ray diffraction (XRD) and extended X-ray absorption fine structure (EXAFS) analyses. Sr-3(PO4)(2):Ce3+ compounds with two different Sr sites (3a and 6c sites) were synthesized using the solid-state reaction method. Single-crystal XRD analysis confirmed the location of Ce at the 3a site along with the corresponding vacancy or coexisting Li at the 6c site. Additionally, the Ce K-edge EXAFS analysis supported the occupancy of Ce3+ at the 3a site rather than at the 6c site.
