Cerium Fluoride Applications
- Scintillation Detectors: Cerium fluoride crystals can function as scintillation detectors to detect and quantify radiation. Cerium fluoride crystals produce visible light when exposed to ionizing radiation, thereby being useful in medical imaging and nuclear physics.
- Laser Crystals: Cerium fluoride crystals can be used as gain media in laser applications, including ultraviolet (UV) lasers. They have been of interest because of possible use in solid-state lasers to utilize in materials like material processing and medical instrumentation.
- Optical Components: Cerium fluoride is used as an optical material in windows, prisms, and lenses. Due to its transparency in the UV and near-UV regions, it is well suited for application in spectroscopy, UV lithography, and UV optical systems.
- Scintillation Screens: Cerium fluoride screens are used in X-ray imaging and fluorescence spectroscopy. They can convert X-ray or high-energy radiation into visible light, facilitating imaging and analysis of biological specimens and materials.
- UV Absorbers: Cerium fluoride nanoparticles are used as UV absorbers in sunscreens and cosmetic lotions. They can absorb and dissipate damaging UV radiation, protecting the skin.
- Phosphors: Cerium fluoride is used to make fluorescent lamp and display phosphor. By adding other rare earth elements, it can be made to emit light of varied colors and hence used in lighting.
- Nuclear Reactors: Cerium fluoride is used as a coolant in some nuclear reactors due to its high melting point and chemical stability at high temperatures. It allows for the extraction of heat from the reactor core.
- Ceramics and Glass: It is used as an additive in ceramic and glass mixtures to improve their properties, such as thermal stability and thermal shock resistance.
- Chemical Catalysts: Cerium fluoride is used as a co-catalyst or catalyst in some catalytic reactions, leveraging its surface reactivity and unique electronic properties.
- Fuel Cells: Cerium fluoride-based materials have been explored for potential use in solid oxide fuel cells (SOFCs) as electrodes or electrolytes.
- Dental and Medical Imaging: Cerium fluoride is used in dental X-ray imaging as a scintillator. It is used to convert X-rays to visible light for the recording of dental images.
- Crystal Growth: Cerium fluoride crystals are crystallized and employed as substrates for the crystal growth of other materials, for example, semiconductor materials.
