Scintillation and dosimeter properties of Tb-doped strontium fluoride transparent ceramics

Luminescence properties of strontium fluoride transparent ceramics with various TbF 3 amounts (0.1, 0.5, and 1 %) were investigated. Scintillation peaks derived from the electronic transitions between 4f levels in Tb 3+ were observed. The observed scintillation decay times of approximately 8.3 ms were typical for the electronic transitions in Tb 3+ . Furthermore, the Tb-doped strontium fluoride transparent ceramics showed thermoluminescence and optically stimulated luminescence (OSL) with Tb 3+ serving as the recombination center. The most intense thermoluminescence signal was detected from the 0.1 % Tb-doped transparent ceramic within the range of 0.01–100 mGy. OSL stimulated by 600 nm light of the same material was the most intense, and its lowest detectable limit was about 100 mGy. • Luminescence properties of Tb-doped strontium fluoride transparent ceramics were investigated. • Tb-doped strontium fluoride transparent ceramics showed scintillation due to the 4f.→4f transitions of Tb 3+ . • Thermoluminescence and optically stimulated luminescence from Tb 3+ were also observed.
