· CsGaS3

CsGaS3 is a ternary semiconductor compound composed of cesium, gallium, and sulfur, belonging to the family of wide-bandgap chalcogenides. This is an emerging research material under investigation for optoelectronic and photonic applications, particularly in the infrared spectrum where its optical transparency and semiconductor characteristics may enable devices beyond the capabilities of more common materials like GaAs or ZnSe.

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.
