Product Introduction
CeF₃ (Cerium Trifluoride ) Crystals are a high-performance magneto-optic crystal product with outstanding overall characteristics. Currently, the most commonly used magneto-optic crystal is terbium gallium garnet (TGG), which plays a critical role in applications such as magneto-optic isolators, modulators, phase shifters, switches, and circulators. However, TGG’s limited transparency in the ultraviolet range (<400 nm) severely restricts its use in UV-related applications. In contrast, CeF₃ crystals belong to the hexagonal crystal system and boast an exceptionally wide transmission window, with a cutoff wavelength below 300 nm—making them a vital material for UV-range magneto-optic devices. Moreover, CeF₃ crystals do not suffer from the "core-shell" issue often encountered in other materials, resulting in high raw material utilization efficiency. CeF₃ crystals also offer several advantageous properties, including high density, excellent thermal stability, superior detection efficiency, and rapid response times. These attributes make them ideally suited as detector materials for high-energy physics experimental setups. As a result, CeF₃ finds extensive applications in fields such as Faraday isolators, X-ray detectors, beta-ray detectors, and gamma-ray detectors. Additionally, CeF₃ is recognized as a scintillating crystal—a promising new class of inorganic scintillators widely employed in medical imaging and high-energy physics. It stands out for its high density, short decay time, and remarkable radiation hardness, further enhancing its versatility and performance in cutting-edge scientific and medical technologies.
Materials like CeF₃ represent a class of outstanding, cutting-edge magneto-optic materials that hold the potential to fundamentally change the current reliance on foreign suppliers for large-scale magneto-optic crystal components. This breakthrough will strongly support the development of China’s high-power all-solid-state lasers and the optical communication industry.
