What is LEAD SELENIDE?

Chemical properties

gray black powder(s); semiconducting material used in infrared detectors and in thermoelectric devices, and as a 99.999% pure material, to produce photoconductive films [HAW93] [STR93] [CER91]

The Uses of LEAD SELENIDE

Lead selenide may be used to prepare PbSe/CdSe core/shell nanocrystal quantum dots (NQDs) applications such as infrared lasers and biological labels. Other applications may be as photodetectors.

The Uses of LEAD SELENIDE

Lead(II) selenide is used in the production of infrared detectors for thermal imaging. It is also used as quantum dots in nanocrystal solar cell. It is an important material and finds applications in photographic plates, and photo resistors and optoelectronic devices.

General Description

Lead selenide has cubic rocksalt crystal structure which undergoes transition at high pressures to orthorhombic structure.2 PbSe is a semiconductor material that emits infrared radiation. Heat capacity of PbSe was evaluated by Kelley-Parks-Huffman method.

Structure and conformation

The space lattice of PbSe belongs to the cubic system, and its rock-salt-type structure has a lattice constant of a=0.614 nm and Pb-Se=0.307 nm.
