· Cu1 Br1

Copper(I) bromide (CuBr) is a semiconductor compound belonging to the I-VII class of binary semiconductors, featuring a zinc-blende crystal structure. This material is primarily investigated in optoelectronic research and specialized photonic applications, where its direct bandgap and strong light-matter interactions make it attractive for UV-visible emission and detection; it is less common in high-volume industrial production compared to more established semiconductors like GaAs or InP, but remains of interest for niche applications in quantum optics, photoluminescence devices, and potential future photovoltaic technologies.

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.
