· Ba2GaSe4

Ba2GaSe4 is a quaternary chalcogenide semiconductor compound composed of barium, gallium, and selenium, belonging to the family of wide-bandgap semiconductors with potential for optoelectronic and photonic applications. This material is primarily of research and development interest rather than established commercial production, studied for its nonlinear optical properties, infrared transmission capabilities, and potential use in mid-infrared photonic devices where conventional semiconductors reach their limitations. Ba2GaSe4 and related barium gallium chalcogenides are explored as candidates for frequency conversion, optical parametric oscillators, and detectors in the infrared spectrum, offering advantages over traditional materials like GaAs in specific wavelength ranges.

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.
