· Ba2YGaSe5

Ba₂YGaSe₅ is a quaternary semiconducting compound belonging to the chalcogenide family, combining barium, yttrium, gallium, and selenium in a fixed stoichiometric ratio. This material is primarily investigated in research contexts for nonlinear optical and optoelectronic applications, particularly where mid-infrared transparency and wide bandgap semiconducting behavior are advantageous. Its relatively uncommon composition reflects emerging interest in multi-element chalcogenides for specialized photonic devices where traditional binary or ternary semiconductors fall short.

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.
