CdSb is a binary III-V semiconductor compound composed of cadmium and antimony, belonging to the family of narrow-bandgap semiconductors used primarily in infrared and photonic applications. Historically employed in infrared detectors, thermal imaging sensors, and photodiodes operating in the mid-to-far infrared spectrum, CdSb offers sensitivity in wavelength ranges where competing materials become ineffective. While largely superseded in mainstream commercial applications by alternatives such as HgCdTe and modern quantum-dot systems due to cadmium toxicity concerns and processing challenges, CdSb remains relevant in specialized research contexts and legacy defense/aerospace systems requiring robust, cost-effective infrared detection at specific wavelengths.
