Barium fluoride (BaF2) is a scintillator showing two wavelengths of emission (310 nm and 295 nm). The emission at 220nm has an emission with sub nanosecond decay time interesting for timing applications. It is used as the fast timing for: Positron Lifetime Studies, Time of Flight measurements, Positron Emission Tomography (PET) and Certain High-energy Physics Applications.
