Barium fluoride (BaF2) crystal belongs to the cubic crystal system, exhibiting excellent moisture resistance, a melting point of 1280°C, and high operating temperatures. Its refractive index remains relatively stable over a broad wavelength range, with a wide transmission spectrum spanning from 0.2 µm to 10 µm, achieving over 90% transmittance. The crystal combines superior optical and mechanical properties. Additionally, BaF₂ demonstrates outstanding scintillation characteristics, featuring both fast and slow luminescence components that enable simultaneous energy spectrum and time spectrum measurements. The fast luminescence component, operating on a sub-nanosecond scale, makes BaF₂ the fastest known inorganic scintillator. This property grants it broad application potential in radiation detection fields such as positron annihilation, material physics, nuclear medicine, ultra-high-speed imaging, and counting.
