Undoped and Tb-doped single crystals of Sr3Y(PO4)3 were synthesized by the floating zone method, and the dosimetric properties of the obtained single crystals were investigated. The undoped crystal displayed a luminescence peak at 360 nm due to self-trapped excitons in both thermally and optically stimulated luminescence (TSL and OSL) spectra. The Tb-doped crystals showed luminescence peaks originating from 4f-4f transitions of Tb3+ in both TSL and OSL spectra. The 1% Tb-doped sample had the highest TSL and OSL intensities. The lower detection limits of TSL and OSL signals of the 1% Tb-doped sample were 0.01 and 0.1 mGy, respectively.
