· Dy1 Tl1 Se2

Dy₁Tl₁Se₂ is a ternary chalcogenide semiconductor compound combining dysprosium, thallium, and selenium. This is a research-phase material primarily of interest in solid-state physics and materials discovery rather than established industrial production; compounds in this family are investigated for potential applications in thermoelectric energy conversion and infrared optics where rare-earth and heavy-metal chalcogenides offer tunable bandgaps and strong light-matter interactions.

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.
