· Te0.4Se0.6

Te0.4Se0.6 is a tellurium-selenium alloy semiconductor belonging to the chalcogenide family, combining these two group XVI elements in a 40:60 composition ratio. This material is primarily investigated in research contexts for infrared (IR) optics, thermal imaging, and thermoelectric applications, where the intermediate bandgap between pure selenium and tellurium offers tailored electronic and optical properties. The alloy is notable for potential use in IR detectors and windows operating in the mid-to-far infrared spectrum, though it remains less common in mainstream industrial production compared to binary elemental semiconductors or more established III-V compounds.

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.
