The double phosphate K3Lu (PO4)2 doped with Pr3+ ions was prepared by solid-state reaction. The material obtained was characterized by X-ray powder diffraction (XRPD). The luminescence spectroscopy and the excited state dynamics of this material were studied for the first time upon excitation with UV-VUV synchrotron radiation (SR). The material has shown efficient and fast Pr3+ 5d-4f emission upon both intra-center and band-gap excitation. A strong dependence of the luminescence spectra as well as the decay kinetics on the temperature was observed due to crystallographic structural phase changes of the K3Lu (PO 4)2 host. © 2013 Elsevier B.V.
