· JVASP-101033· YbF3

Ytterbium trifluoride (YbF₃) is a rare-earth fluoride ceramic compound that belongs to the family of lanthanide fluorides, characterized by high chemical stability and thermal resistance. It is primarily used in optical and photonic applications, particularly as a host material for laser crystals (such as Yb-doped fiber lasers and solid-state lasers) and as a component in fluoride glass systems for infrared optics. YbF₃ is valued in specialized contexts where its optical transparency in the near-infrared and mid-infrared regions, combined with chemical inertness in corrosive environments, offers advantages over conventional oxides and halides, though it remains largely confined to research and high-performance photonics rather than commodity applications.
