metal· JVASP-56315· BaAg2GeSe4
BaAg₂GeSe₄ is a quaternary chalcogenide compound combining barium, silver, germanium, and selenium—a member of the metal chalcogenide family with mixed-valence metallic character. This is a research-phase material investigated primarily for nonlinear optical and photonic applications, where the combination of heavy elements and chalcogenide structure offers potential for mid-infrared transparency and second-harmonic generation. Engineers and materials scientists are exploring such compounds for specialized optoelectronic devices where conventional semiconductors or oxides cannot meet performance requirements in specific wavelength windows.

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.
