As a good Faraday rotator single-crystals, cerium fluoride (CeF3) have attracted much attention in the field of magneto-optics due to their broad applications such as optical isolators. The magneto-optical effects of the Ce ions are known to be caused by the intra-ionic parity allowed electric dipole transition between the 4fN and 4fN-15d1 configurations. These transitions are close to the absorption cut-off in the widely transparent fluorides, which leads to outstanding Verdet constants in the UV wavelength region. It is a good scintillation crystal with high density and short decay time. CeF3 Crystal is a suitable material in the measurements application of high counting rate, strong absorption irradiation and high time resolution process.
