BaF2 Barium Fluoride
Barium fluoride (BaF2) has an emission component with subnanosecond decay time that yields very fast timing. It 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. Using special electronics, time resolutions around 200 ps are possible for small detector geometries.
There are several other scintillators that also have excellent timing capabilities. These are BrilLanCeTM 380 and 350 (LaBr3:Ce and LaCl3:Ce) and LYSO scintillators.
