Na1 Sm1 Se2
semiconductor· Na1 Sm1 Se2
Sodium samarium diselenide (Na₁Sm₁Se₂) is a rare-earth halide semiconductor compound combining sodium, lanthanide (samarium), and selenium elements. This is a research-phase material primarily investigated for its electronic and optical properties rather than established industrial production; compounds in this family are explored for solid-state ion conductivity, photovoltaic applications, and thermoelectric devices where rare-earth selenides offer tunable band gaps and potential thermal stability advantages over conventional semiconductors.

Export Control
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.
