Lead Selenide (PbSe)-Powder

Characteristic




Lead selenide (PbSe), or lead(II) selenide, a selenide of lead, is a semiconductor material. It forms cubic crystals of the NaCl structure; it has a direct bandgap of 0.27 eV at room temperature. 




Chemical formula：PbSe

CAS#:12069-00-0

Molar mass：286.16 g/mol

Melting point：1,078 °C (1,972 °F; 1,351 K)

Crystal structure：Halite (cubic), cF8




Application




It is used for manufacture of infrared detectors for thermal imaging, operating at wavelengths between 1.5–5.2 μm. It does not require cooling, but performs better at lower temperatures.
