Abstract
Present work describes the first detailed γ-ray light yield of Ce3+ perturbed emission in CaF2 host. (1-, 3-, 5-, 10-, and 20-mol %-) Ce3+-doped single crystalline CaF2 scintillator crystals were grown by the micro-pulling-down method. Their transmittances were measured to be approximately 80% at UV to visible wavelengths. All the crystals exhibited emission peaks at approximately 330 nm, which were identified as the Ce3+ perturbed emission, when they were irradiated by 1 GBq 137Cs. The photoluminescence decay kinetics was measured to be about 40 ns for all the crystals. Scintillation light yield in unit of photons/MeV (ph/MeV) was measured, and the 5% sample showed the highest light yield of around 900 ph/MeV with 2 µs shaping time.
