· Ba2GaYSe5

Ba2GaYSe5 is a quaternary semiconductor compound combining barium, gallium, yttrium, and selenium—a mixed-metal chalcogenide belonging to the broader family of wide-bandgap semiconductors. This is a research-phase material primarily investigated for nonlinear optical and infrared photonic applications, where its crystal structure and electronic properties offer potential advantages in frequency conversion, mid-infrared detection, and quantum optics compared to conventional semiconductors like GaAs or commercial nonlinear crystals.

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.
