ceramic

· JVASP-10074· YbOF

YbOF is an oxyfluroride ceramic compound containing ytterbium, oxygen, and fluorine. It belongs to the rare-earth oxyfluroride family, which are primarily investigated as optical and photonic materials for specialized applications requiring high refractive index contrast and low phonon energies. This material is of research interest rather than established in high-volume manufacturing, with potential applications in infrared optics, laser systems, and optical fibers where thermal stability and transparency in specific wavelength ranges are critical.
