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.
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.

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.

The self-assembly of colloidal nanocrystals into ordered superstructures depends critically on the shape of the nanocrystal building blocks. We investigated the self-assembly of cubic PbSe nanocrystals from colloidal suspensions in real-time using in situ synchrotron-based X-ray scattering. We combined small-angle
