· Cd1 Ag2 I4

Cd₁Ag₂I₄ is a ternary semiconductor compound combining cadmium, silver, and iodine in a layered crystal structure. This material belongs to the family of halide semiconductors and is primarily of research interest for optoelectronic and photonic applications, particularly in X-ray and gamma-ray detection where its high atomic number iodine content provides strong radiation interaction. While not yet commercialized at scale, cadmium-silver-iodide semiconductors are investigated as alternatives to cadmium telluride and lead halide perovskites due to their tunable bandgap and potential for high-efficiency photon detection in medical imaging, nuclear monitoring, and space instrumentation.

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.
