Dosimetric Properties of Tm-doped CaGdAlO4

Year: 2026

Type: article

Abstract: The photoluminescence (PL) and dosimetric properties of Tm-doped CaGdAlO 4 single crystals were investigated.The samples exhibited the luminescence arising from the 4f-4f transitions of Tm 3+ .Thermally stimulated luminescence (TSL) glow curve measurements revealed that Tm doping into the CaGdAlO 4 lattice introduced new trapping centers.The 1% Tm-doped CaGdAlO 4 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 CaGdAlO 4 was 1 mGy.
