YbLiAlF6
metal· JVASP-21570· YbLiAlF6
YbLiAlF6 is a rare-earth fluoride compound combining ytterbium, lithium, aluminum, and fluorine—a synthetic crystalline material belonging to the fluoride family rather than a traditional metal alloy. This compound is primarily studied and used in photonics and laser applications, particularly as a host material for rare-earth dopants (such as Er³⁺ or Yb³⁺ ions) in solid-state lasers and optical amplifiers. Its fluoride matrix offers excellent optical transparency, low phonon energy, and high thermal stability, making it attractive for next-generation fiber lasers and amplified spontaneous emission (ASE) sources where conventional oxide or silicate hosts prove inadequate.

Export Control
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
