· TlGaSe2

TlGaSe2 is a ternary III-VI semiconductor compound composed of thallium, gallium, and selenium, belonging to the family of layered chalcogenide semiconductors. This material is primarily investigated in research contexts for infrared optics and nonlinear optical applications, where its wide bandgap and anisotropic crystal structure enable efficient light modulation and frequency conversion in the mid- to far-infrared spectrum. While not yet widely deployed in mainstream industrial production, TlGaSe2 represents a promising alternative to conventional crystals like cadmium telluride and selenium for specialized optoelectronic devices where thermal stability, optical transparency, and nonlinear response are critical—making it of particular interest to researchers developing tunable lasers, infrared detectors, and parametric amplifiers.

Export 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.
