Tb-doped Ca3TaGa3Si2O14 (CTGS) single crystals with different concentrations were synthesized to evaluate their photoluminescence and radioluminescence properties. All the samples showed emissions due to the 4f–4f transitions of Tb3+. The 2% Tb-doped sample showed the highest quantum yield of 16.4% upon excitation at 350 nm. Decay curves demonstrated decay time constants of 2.0–2.1 ms, which were the typical values for the 4f–4f transitions of Tb3+.
