· JVASP-37705· PbSe2

PbSe2 is a lead selenide ceramic compound belonging to the chalcogenide family of semiconductors. It is primarily investigated for thermoelectric and infrared sensing applications, where its narrow bandgap and high charge carrier mobility make it attractive for converting waste heat to electricity or detecting thermal radiation in the mid-to-long-wavelength infrared region. While not yet widely deployed in high-volume production, PbSe2 and related lead chalcogenides offer potential advantages over traditional thermoelectric materials and infrared detectors in specialized aerospace, thermal imaging, and energy recovery applications, though toxicity concerns and cost relative to alternatives currently limit adoption.
