ceramic

· JVASP-25647· YbClF

YbClF is a rare-earth halide ceramic compound combining ytterbium, chlorine, and fluorine elements. This material belongs to the family of mixed-halide ceramics, which are primarily of research interest for optical and photonic applications due to the luminescent properties of ytterbium ions. While not yet widely established in high-volume industrial production, YbClF and related rare-earth halides show promise in solid-state laser materials, scintillators, and potentially in thermal or radiation-resistant ceramic applications where rare-earth dopants provide functional performance.
