CeF3 crystal is a magneto-optical crystal product with excellent comprehensive performance. The magneto-optical properties of CeF3 crystal enable it to be used as a Faraday rotator used in the field of high-power lasers. It has the advantages of high density, good temperature stability, high detection efficiency and fast response speed, making it very suitable as a detection material for high-energy physics experimental devices, X-ray detectors, β-ray detectors and γ-ray detectors. At the same time, CeF3 is also a scintillation crystal, a new inorganic scintillator used in medical imaging and high-energy physics.
