· Ba4 Y2 Br14

Ba₄Y₂Br₁₄ is a mixed halide perovskite semiconductor composed of barium, yttrium, and bromide ions, representing an emerging class of materials in halide perovskite research. This compound is primarily investigated in academic and industrial research settings for optoelectronic applications, particularly where the combination of rare-earth doping (yttrium) and alkaline-earth host (barium) may offer enhanced stability, tunability, or photoluminescent properties compared to archetypal lead or tin halide perovskites. The bromide-rich composition positions it as a candidate for visible-light emission and radiation detection, though practical deployment remains limited and largely experimental.

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.
