HoF3

Holmium fluoride (HoF3) is an inorganic ceramic compound composed of the rare-earth element holmium and fluorine, belonging to the rare-earth fluoride family of materials. It is primarily used in optics and photonics applications, particularly as a host material for laser crystals and luminescent devices that operate in the infrared spectrum. This material is valued for its optical transparency in the IR region and its ability to incorporate rare-earth dopants, making it relevant for specialized applications where conventional optical ceramics are insufficient, though it remains largely confined to research and high-end photonics rather than mainstream industrial use.
