The optical, thermally stimulated luminescence (TSL), and optically stimulated luminescence (OSL) properties of CsBr:Cu transparent ceramics were evaluated. As the photoluminescence properties, two emissions around 460 and 490 nm related to Cu+ and Cu2+ ions, respectively, were observed under excitation at around 300 nm, and the quantum yield of CsBr:Cu (0.01%) was 17.3%. After X-ray irradiation, all the samples showed a broad TSL and OSL emission band around 400–500 nm. All the samples exhibited good proportionality in the TSL and OSL dose response functions in the dose ranges of 0.01–100 and 1–1000 mGy, respectively.
