Scintillation Properties of Tb-doped SrLu2O4 Single Crystals

Tb-doped SrLu2O4 single crystals were grown by the floating zone method, and their optical and scintillation properties were evaluated. Regarding the scintillation properties, all the prepared crystals showed the sharp emission peaks assigned to Tb3+ 4f–4f transitions in the range of 350–650 nm. The...

Zusammenfassung:Tb-doped SrLu2O4 single crystals were grown by the floating zone method, and their optical and scintillation properties were evaluated. Regarding the scintillation properties, all the prepared crystals showed the sharp emission peaks assigned to Tb3+ 4f–4f transitions in the range of 350–650 nm. The obtained decay times of 1.0–1.6 ms were typical values for the Tb3+ 4f–4f transitions. From the results of the pulse area spectra, the 1.0% Tb-doped crystal showed the highest light yield of 19600 photons/MeV among the prepared crystals.
