Abstract Ce3+-doped Sr9Lu(PO4)7 polycrystalline material has been synthesized using a solid state reaction at high temperature. Luminescence spectroscopic properties and emission decay kinetics have been studied upon UV-VUV excitation. Emission from Ce3+ ions located in two types of crystallographic sites has been identified in low-temperature spectra. Ce3+ ions have been shown to prefer occupying Sr2+ sites rather than Lu3+ sites. The temperature-dependent decay curves of Ce3+ 5d→4f emission demonstrate an excellent luminescence thermal stability.
