Sm1 Tl1 Se2
semiconductor· Sm1 Tl1 Se2
SmTlSe₂ is a ternary chalcogenide semiconductor compound combining samarium (a rare earth element), thallium, and selenium. This is a research-phase material rather than a commercially established compound, belonging to the broader family of rare-earth-based semiconductors being investigated for specialized optoelectronic and solid-state device applications. The material's semiconducting behavior and rare-earth content make it potentially interesting for narrow-bandgap or infrared applications, though its practical use remains largely confined to experimental work in condensed-matter physics and materials research laboratories.

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.
