· Tl2InGaSe4

Tl2InGaSe4 is a quaternary chalcogenide semiconductor compound composed of thallium, indium, gallium, and selenium. This material belongs to the family of ternary and quaternary semiconductors with layered or diamond-like crystal structures, primarily investigated in research contexts for optoelectronic and nonlinear optical applications. While not yet widely deployed in commercial products, materials in this compositional space are of interest for infrared detection, frequency conversion, and photonic devices where bandgap engineering and crystalline quality can be tailored through stoichiometric control.

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.
