· Ho1 Bi2 Cl1 O4

Ho₁Bi₂Cl₁O₄ is a rare-earth bismuth oxyhalide semiconductor, a mixed-valence compound combining holmium and bismuth with chloride and oxide anions. This material belongs to an emerging class of layered halide perovskites and bismuth-based semiconductors being investigated for optoelectronic and photocatalytic applications. Currently in the research phase rather than established in high-volume manufacturing, this compound shows promise in the broader family of lead-free semiconductors due to its potential for tunable bandgap and photocatalytic activity under visible light.

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.
