Ba-fresnoite Single-crystalline Scintillator for X-ray Detection

Scintillation detectors, composed of scintillators and photodetectors, have recently been applied in various fields.Since the performance of scintillation detectors mainly depends on that of the scintillator, the development of more advanced scintillators is still ongoing.In this study, Ba-fresnoite is focused on as a new scintillator and its performance is evaluated.Ba-fresnoite shows an emission band centered at 460 nm with decay time constants of 1.0 and 3.7 ms, and the light yield is 5100 photons/MeV.
