· Cd0.3Hg0.7Se1

Cd₀.₃Hg₀.₇Se is a cadmium-mercury-selenide ternary semiconductor alloy belonging to the II-VI compound semiconductor family, engineered to achieve specific bandgap properties through compositional tuning of the cadmium-mercury ratio. This material is primarily investigated for infrared (IR) detection and imaging applications, where its narrow bandgap enables sensitivity in the mid-to-long-wavelength IR spectrum; it represents an established materials platform in the mercury-cadmium-telluride (HgCdTe) family lineage, though with selenide substitution for different spectral response characteristics. The alloy's primary advantage over alternatives is wavelength tunability through composition control, making it valuable for thermal imaging, astronomy, and spectroscopic sensing where competing materials (silicon, InGaAs) have insufficient IR sensitivity.

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.
