About Cadmium Selenide CdSe Powder :
Cadmium selenide is an inorganic compound with the molecular formula CdSe.What is the name of CdSe? Cadmium selenide. It is a black to red-black solid and is classified as an N-type semiconductor II-VI.So far, research on the salt has focused on its nanoparticles. Cadmium selenide (CdSe) is a hexagonal modified tetrahedral semiconductor with a wurtzite structure.CdSe is a uniaxial optical semiconductor with two dielectric functions. The measurement of the reflectivity spectra of CdSe crystals under the action of polarized light shows that the electric vectors parallel to and perpendicular to the hexagonal axis are quite different.
Cadmium selenide is a solid binary compound of cadmium and selenium. It is an n-type semiconductor material that is transparent to infrared light. However, p-type doping of cadmium selenide occurs in the use of nitrogen. Wurtzite, sphalerite and rock salt are the three known forms of cadmium selenide crystals. Cadmium is a toxic heavy metal, and selenium can be toxic in large amounts. Cadmium selenide is therefore a known carcinogen in humans and requires medical attention if swallowed or if it comes into contact with the eyes and skin. Most of the current research work focuses on development control.
What is Cadmium Selenide structure? CdSe comes in three crystalline forms: hexagonal wurtzite (hexagonal), galena (cubic), and halite (cubic). The CdSe structure of sphalerite is unstable and converts to wurtzite after moderate heating. The transition starts at around 130 ° C and can be completed in a day at 700 ° C.Halite structures are only observed at high pressures.

How is Cadmium Selenide CdSe Powder produced?
Cadmium selenide (cadmium selenide synthesis) is produced in two different ways. Bulk crystalline CdSe was prepared by high-pressure vertical Bridgman method or high-pressure vertical zone melting method
CdSe can also be produced in the form of nanoparticles. There are several methods for preparing CdSe nanoparticles: retention precipitation in solution, synthesis of structural media, pyrolysis at high temperature, ultrasonochemistry, and radiolysis
Under controlled conditions, alkyl cadmium and tri octyl phosphine selenide (TOPSE) precursors were introduced into a heated solvent, and cadmium selenide was prepared by retention precipitation in a solution
ME2Cd + TOPSE →CdSe +(by-product)
High-temperature pyrolytic synthesis is usually carried out using aerosols containing volatile mixtures of cadmium and selenium precursors. The precursor aerosol is then brought into a furnace containing inert gases such as hydrogen, nitrogen or argon. The precursor reacts in the furnace to form CdSe and several by-products.
Applications of Cadmium Selenide CdSe Powder:
CdSe materials are transparent to infrared (IR) light and have limited applications in photoresistors and Windows of instruments that utilize infrared light. The material also has high luminescent properties.CdSe is a component of the pigment cadmium orange.
Cadmium selenide uses are also including:
High-efficiency solar cell
