· Ba5(GaSe4)2

Ba5(GaSe4)2 is a complex barium gallium selenide compound belonging to the family of wide-bandgap semiconductors, which combines earth-abundant elements in a layered crystal structure. This is a research-phase material primarily explored for nonlinear optical applications and mid-infrared photonics, where its combination of wide transparency window and second-harmonic generation capability makes it potentially valuable as an alternative to conventional infrared crystals like GaAs or ZnSe.

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.
