Undoped and Tm-doped NaMgF3 single crystals were synthesized and investigated in terms of their scintillation and optically stimulated luminescence (OSL) properties. The synthesized samples were confirmed to be a single-phase NaMgF3 by X-ray diffraction (XRD). The Tm-doped sample showed the X-ray-induced scintillation spectrum characterized by sharp emission lines owing to the 4f-4f transitions of Tm3+. The OSL spectrum of the Tm-doped sample also showed emission at around 360 nm, which was ascribed to the 4f-4f transitions of Tm3+. The OSL dose response function of the Tm-doped sample showed a linear response at the dose range of 1–10000 mGy.
