· AgGaSe2

AgGaSe₂ is a ternary semiconductor compound belonging to the I–III–VI₂ family, combining silver, gallium, and selenium in a chalcopyrite crystal structure. It is primarily investigated for infrared (IR) optoelectronic applications, particularly as a nonlinear optical material and IR detector, and has been explored in mid-to-far infrared imaging systems where its wide bandgap and nonlinear properties offer advantages over traditional germanium or lead-chalcogenide alternatives for specialized 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.
