Er3F

Er3F is a rare-earth fluoride ceramic composed of erbium and fluorine, belonging to the family of lanthanide fluoride compounds. These materials are typically investigated for optical, thermal, and specialized functional applications where fluoride's low phonon energy and erbium's luminescent properties provide advantages over oxide ceramics. Er3F systems are primarily of research and emerging industrial interest, particularly in photonics, solid-state laser technology, and high-temperature thermal management where conventional ceramics fall short.
