General description
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Find details here.
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.
Application
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.

Field-effect transistors are fabricated from thin films of Ag-doped PbSe nanocrystals to analyze the influence of electronically active impurities on electrical transport in this important material for nanocrystal applications. Data is collected as a function of nanocrystal size, dopant concentration
