· CdSb2Se3Br2

CdSb2Se3Br2 is a mixed-halide cadmium chalcogenide semiconductor compound combining antimony, selenium, and bromine in a layered or three-dimensional crystal structure. This is a research-phase material primarily investigated for optoelectronic and photovoltaic applications, where the mixed halide composition offers tunable bandgap and enhanced light absorption compared to single-halide alternatives. The material family is relevant to next-generation solar cells, photodetectors, and radiation detection devices where cadmium chalcogenides provide high atomic number sensitivity and favorable band alignment.

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.
