· Ba1 Sr1 I4

Ba₁Sr₁I₄ is a halide perovskite semiconductor compound combining barium, strontium, and iodine in a layered crystal structure. This material is primarily investigated in research contexts for next-generation optoelectronic and photovoltaic applications, where the mixed-cation composition offers potential for tuned bandgap and improved stability compared to single-cation iodide perovskites. Engineers consider halide perovskites like this compound for applications requiring low-cost solution processing, high light absorption, and tunable electronic properties, though commercialization remains limited due to ongoing challenges with long-term stability and lead-free alternatives.

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.
