· Sr2 Ca2 I8

Sr₂Ca₂I₈ is a halide perovskite semiconductor compound combining strontium, calcium, and iodine in a layered crystal structure. This material is primarily of research interest rather than established commercial use, investigated for optoelectronic applications where its bandgap and electronic properties may offer advantages in light emission, detection, or photovoltaic devices compared to lead-based halide perovskites. Engineers evaluating this compound should recognize it as an emerging material in the halide perovskite family, with potential relevance to next-generation semiconductor devices seeking lead-free or toxicity-reduced 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.
