· Tl8 Cd2 I12

Tl₈Cd₂I₁₂ is a mixed-halide semiconductor compound combining thallium, cadmium, and iodine in a layered perovskite or perovskite-derivative crystal structure. This is a research-phase material investigated for optoelectronic and radiation detection applications, belonging to the broader family of multinary halide semiconductors that show promise for tunable bandgaps and strong light-matter interactions. The material is notable within the halide perovskite research community as a candidate for X-ray and gamma-ray detection, photovoltaic energy conversion, and solid-state scintillation due to its high atomic number constituents and potential for defect-tolerant carrier transport, though it remains in early-stage development and is not yet widely commercialized.

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.
