Comparison of Scintillation Performance of Ca3TaGa3Si2O14 and Ca3TaAl3Si2O14 Single Crystals

Year: 2026

Type: article

Abstract: Ca 3 TaGa 3 Si 2 O 14 (CTGS) and Ca 3 TaAl 3 Si 2 O 14 (CTAS) single crystals were grown by the f loating zone method, and their photoluminescence and scintillation properties were investigated.The CTGS and CTAS samples showed broad emission bands at 300-600 nm under UV light and X-rays, and the decay time constants were of ms order.From the afterglow curves after X-ray irradiation for 2 ms, the afterglow levels at 20 ms were 30 ppm for CTGS and 40 ppm for CTAS.The pulse height spectra of 137 Cs γ-rays measured using the CTGS and CTAS demonstrated that the calculated light yields of CTAS and CTGS were 1200 and 600 photons/ MeV, respectively.
