· CsYZnSe3

CsYZnSe₃ is a ternary chalcogenide semiconductor compound composed of cesium, yttrium, zinc, and selenium, belonging to the family of metal selenide semiconductors. This material is primarily investigated in research settings for optoelectronic and photonic applications, particularly in the infrared spectral region where selenide compounds offer wide bandgap tunability and optical transparency. The cesium-yttrium-zinc selenide system is notable for potential use in mid-infrared detectors, nonlinear optical devices, and radiation detection, where the combination of constituent elements enables properties distinct from binary zinc selenide or ternary zinc chalcogenides commonly used in industry.

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.
