· Na2BaGeS4

Na2BaGeS4 is a quaternary chalcogenide semiconductor compound combining sodium, barium, germanium, and sulfur in a crystalline structure. This is a research-phase material investigated for infrared optics and photonic applications, where its wide bandgap and transparency window in the mid-infrared region are valuable for wavelengths inaccessible to conventional semiconductors. The material represents the broader family of sulfide-based chalcogenides, which offer advantages over oxide counterparts in thermal stability and refractive index, though industrial adoption remains limited compared to established alternatives like zinc sulfide or gallium arsenide.

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.
