Rb4 Ca4 I12
semiconductor· Rb4 Ca4 I12
Rb₄Ca₄I₁₂ is a halide perovskite semiconductor compound combining rubidium, calcium, and iodine in a layered crystal structure. This is a research-phase material belonging to the broader family of metal halide perovskites, which are being actively investigated for optoelectronic applications due to their tunable bandgap, strong light absorption, and potential for solution-based manufacturing. The inclusion of both alkali (Rb) and alkaline-earth (Ca) cations creates a mixed-cation framework that may offer improved structural stability and ion-migration resistance compared to single-cation halide perovskites.

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.
