Ba2YF7
ceramic· JVASP-50818· Ba2YF7
Ba2YF7 is a barium yttrium fluoride ceramic compound belonging to the rare-earth fluoride family, known for high optical transparency and low phonon energy in the infrared spectrum. This material is primarily investigated for photonic and laser applications, particularly as a host matrix for rare-earth dopants in solid-state lasers and optical amplifiers, where its fluoride composition offers superior performance compared to oxide ceramics in the mid-infrared region. Ba2YF7 represents an active research material rather than a widespread industrial commodity, with potential applications in upconversion phosphors and optical devices where efficient energy transfer and minimal thermal quenching are critical.

Regulatory Screening
Environmental
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.
