· Rb1 Ca1 I3

RbCaI₃ is a mixed-halide perovskite semiconductor composed of rubidium, calcium, and iodine. This is an experimental material under investigation for optoelectronic applications, particularly as a variant within the broader perovskite family known for tunable bandgap and solution-processability. The incorporation of alkaline earth (calcium) and alkali (rubidium) cations represents an attempt to improve stability, phase purity, and device performance compared to conventional lead-halide perovskites, though commercial adoption remains limited and material properties are still being characterized by the research community.

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.
