Abstract

The scintillators with Ce luminescent centers are widely used for radiation detection. In this study, we focused on the Ce₂Si₂O₇ pyrosilicate scintillator and evaluated its optical and scintillation properties. From the result of the temperature dependence of quantum yield of Ce₂Si₂O₇ under excitation into the Ce³⁺ 4f-5d₁ transition, it was revealed that at 300°C the Ce₂Si₂O₇ had a quantum yield of approximately 40% of that at the room. In addition, Ce₂Si₂O₇ had a light output of 9,400 ± 800 photons/MeV and fast decay time (~34 ns) at room temperature, and therefore, it has potential for application in radiation detection.
