· K2Hg3S1.03Se2.97

K2Hg3S1.03Se2.97 is a mixed-chalcogenide semiconductor compound combining potassium, mercury, sulfur, and selenium in a quaternary phase. This is a research-level material within the mercury chalcogenide family, which has been explored for infrared sensing and photonic applications due to the tunable bandgap achievable through sulfur-selenium substitution. The sulfur-selenium mixed anion system allows engineers to optimize optical and electronic properties for detection in the infrared spectrum, though such quaternary compositions remain primarily in academic investigation rather than established industrial production.

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.
