The photoluminescence (PL) and dosimetric properties of Tm-doped CaGdAlO4 single crystals were investigated. The samples exhibited the luminescence arising from the 4f–4f transitions of Tm3+. Thermally stimulated luminescence (TSL) glow curve measurements revealed that Tm doping into the CaGdAlO4 lattice introduced new trapping centers. The 1% Tm-doped CaGdAlO4 showed the highest TSL intensity as well as PL quantum yield. The minimum detectable dose in the TSL dose–response function of the 1% Tm-doped CaGdAlO4 was 1 mGy.
