· Dy1 Bi2 Br1 O4

Dy₁Bi₂Br₁O₄ is a mixed-metal oxide-halide semiconductor compound containing dysprosium, bismuth, bromine, and oxygen. This is an experimental/research-stage material rather than an established commercial product; it belongs to the family of rare-earth and post-transition metal halide perovskites and hybrid compositions that are under investigation for optoelectronic and photonic applications. Materials in this compositional space are of interest because they combine rare-earth luminescence properties (dysprosium) with the semiconducting and structural characteristics of bismuth halides, potentially enabling novel photocatalytic, scintillation, or light-emission devices with tunable bandgaps.

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.
