CaF2(Eu) Scintillator

Calcium fluoride doped with europium (CaF₂:Eu) is a well-established inorganic scintillation crystal prized for its chemical stability, non-hygroscopic nature, and mechanical robustness. Under ionizing radiation, it exhibits intense blue luminescence centered around 420–435 nm, originating from the 5d–4f transition of Eu²⁺ ions, with a high light yield of approximately 19,000 photons/MeV and a fast decay time near 0.94 μs. Its low effective atomic number and minimal backscattering make it particularly suitable for beta-particle detection, low-energy gamma-ray spectroscopy, and specialized applications such as tritium monitoring and dark matter searches.
