Ba2 Sr2 I8
semiconductor· Ba2 Sr2 I8
Ba₂Sr₂I₈ is a mixed halide perovskite semiconductor compound combining barium, strontium, and iodine in a layered crystal structure. This material is primarily of research interest for optoelectronic applications, particularly in next-generation photovoltaic devices and radiation detection, where the wide bandgap and high atomic number of the iodide component offer potential advantages over traditional single-cation halide perovskites. The dual-cation composition (barium and strontium) allows tuning of electronic properties and improved phase stability compared to monovalent perovskite alternatives, though the material remains largely in the development stage rather than established industrial production.

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.
