BaF2 – Barium Fluoride
In addition to its use as an UV-Vis-IR optical material, Barium Fluoride’s properties make it ideal for scintillation. BaF2 is utilized widely in high energy physics, nuclear physics and nuclear medical instrumentation.
A fast scintillator, Barium Fluoride’s luminescence intensity is independent of its temperature, with a faster emission from 180nm to 240nm and a slower emission at 310nm.
Excellent radiation hardness is exhibited up to 105 rad, making it useful in nuclear detection with high counting rates and high radiation.
