· Cs2Hg3I8

Cs₂Hg₃I₈ is a mixed-halide perovskite semiconductor compound composed of cesium, mercury, and iodine. This material belongs to the family of lead-free halide perovskites, which are investigated as environmentally safer alternatives to conventional lead-based perovskites for optoelectronic applications. Currently in the research stage, Cs₂Hg₃I₈ is primarily of interest in photovoltaic and radiation detection research contexts, where non-toxic perovskite semiconductors are sought to replace toxic lead-based compounds while maintaining favorable bandgap and light-absorption properties.

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.
