· Fe2 Se2 Br14

Fe₂Se₂Br₁₄ is a mixed-halide iron selenide compound in the semiconductor family, synthesized primarily for materials research rather than established commercial production. This experimental composition combines iron, selenium, and bromine in a structure that bridges the gap between chalcogenide and halide perovskite semiconductors, making it of interest for optoelectronic and photovoltaic research where tunable bandgap and layered crystal structures are desirable. Engineers and researchers investigating this material are typically exploring next-generation photovoltaic absorbers, light-emitting devices, or radiation detection applications where the heavy halide composition and mixed anionic framework offer electronic properties difficult to achieve in conventional semiconductors.

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.
