· Cd0.8Hg0.2Se1

Cd₀.₈Hg₀.₂Se is a cadmium-mercury-selenide ternary alloy semiconductor belonging to the II-VI compound family, engineered by tuning the cadmium-to-mercury ratio to adjust the bandgap and lattice properties. This material is primarily investigated for infrared optoelectronic devices, particularly long-wavelength infrared (LWIR) detectors and thermal imaging applications, where the mercury content lowers the bandgap relative to pure CdSe, enabling sensitivity in the 8–14 μm atmospheric window. The Hg-containing composition offers improved performance over binary alternatives in cryogenic or room-temperature infrared sensing, though it remains primarily a research and specialized aerospace/defense material due to mercury toxicity concerns and the dominance of HgCdTe in established LWIR markets.

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.
