· CsAuBr3

CsAuBr₃ is a cesium gold bromide compound belonging to the family of halide perovskites and intermetallic compounds, combining precious metal (gold) with alkali metal (cesium) and halide (bromine) components. This is a research-phase material primarily investigated for optoelectronic and photonic applications, including potential use in photodetectors, scintillators, and radiation detection due to gold's high atomic number and strong X-ray/gamma-ray interaction cross-section. Its halide perovskite structure makes it notable for studying tunable bandgaps and light-matter interactions, though commercial adoption remains limited compared to more established semiconductors and detection materials.

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.
