0.1% BaCl2:Ce and BaCl2:Eu transparent ceramics were synthesized by the spark plasma sintering method, and the optical and dosimetric properties of BaCl2:Ce and BaCl2:Eu were compared. BaCl2:Ce and BaCl2:Eu transparent ceramics showed photoluminescence (PL) and optically stimulated luminescence (OSL) peaks at around 380 nm due to the 5d–4f transition of Ce3+ and Eu2+. The PL quantum yields of BaCl2:Ce and BaCl2:Eu transparent ceramics were 3.8 and 25.6%, respectively. The PL decay times of BaCl2:Ce and BaCl2:Eu were 21 and 400 ns, respectively. In OSL dose responses, the BaCl2:Eu sample showed better OSL intensity than BaCl2:Ce, and the OSL signal was detectable from 0.01 mGy. In terms of detection sensitivity, this value was comparable to those of some commercially available materials.
