Abstract

The paper presents the synthetic procedure and the structural characterisation of Pr3+-doped eulytite double phosphates Sr3La(PO4)3 and Ba3Lu(PO4)3. The luminescence properties of these materials were studied employing time-resolved VUV spectroscopy upon excitation with synchrotron radiation. The 5d-4f emission of Pr3+ ions was detected and assigned. It was shown that energy transfer from host to Pr3+ 5d states is quite inefficient. At the same time the materials demonstrate unwanted defect-related emission that presents main path for relaxation of host relaxation excitations.
