· Na1 S2 Er1

Na₁S₂Er₁ is a ternary chalcogenide semiconductor compound combining sodium, sulfur, and erbium—a research-phase material that belongs to the rare-earth sulfide family. While not yet in widespread commercial production, materials in this class are investigated for optoelectronic and photonic applications, particularly where rare-earth dopants enable luminescence, upconversion, or mid-infrared activity. Engineers consider such compounds when designing specialized sensors, quantum devices, or optical systems that require the unique electronic and optical properties that rare-earth incorporation provides over binary sulfide alternatives.

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.
