· Cu1 Br2

Copper(I) bromide (CuBr) is an inorganic semiconductor compound consisting of copper and bromine in a 1:1 stoichiometric ratio. This material belongs to the family of copper halide semiconductors, which exhibit direct bandgap properties and relatively high charge carrier mobility, making it of interest for optoelectronic and photonic applications. CuBr remains primarily in the research and development phase, where it is being investigated for potential use in UV-visible light emission, scintillation detectors, and photonic devices; while industrial deployment remains limited compared to more mature semiconductor platforms, the material's tunable electronic properties and potential for cost-effective processing have sustained academic and specialized industrial interest.

Export Control

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.
