Abstract Different concentrations of Eu doped LiMgAlF6 samples were synthesized by the spark plasma sintering (SPS) method. In photoluminescence (PL) measurements, emission due to 5d-4f transition of Eu2+ was observed at 370 nm, and PL decay times resulted 1.1–2.8 μs. When we irradiated X-rays, scintillation emissions due to Eu2+ and Eu3+ were detected at 370 and 600 nm, respectively. Optically stimulated luminescence (OSL) and thermally stimulated luminescence (TSL) were also observed in Eu-doped LiMgAlF6, and especially, TSL intensity was very high.
