What is Cadmium selenide?
Cadmium selenide is an inorganic compound with a chemical formula of CdSe, which is mainly used as an electron emitter, spectral analysis, photoconductor, semiconductor, photosensitive element, and so on. It has a molecular formula of CdSe and a molecular weight of 191.36. It is a grayish-brown or red crystal. Cadmium selenide can be prepared by co-heating metal cadmium with hydrogen selenide. It can also be obtained by directly combining the metal cadmium with selenium at high temperatures.

More about Cadmium selenide
Melting point: 1350℃
Density: 5.81g/cm3
Appearance: grayish brown or red crystals.
Solubility: insoluble in water
Use of Cadmium selenide 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.
In addition, cadmium selenide (CdSe) crystal has infrared transmission characteristics as high as 24μm, with considerable nonlinearity (d31 = 18 pm/V) and a small exit angle. CdSe crystal can be applied to differential frequency generation (DFG) and optical parametric oscillation (OPO) schemes, providing infrared laser radiation beyond the absorption edge of 12 μ m. For example, CdSe OPO may be pumped by 2μm Tm-doped, Ho-doped, Tm-and Ho-co-doped lasers and generate long infrared idling radiation. In addition to nonlinear optical applications, cadmium selenide crystal materials can also be used in infrared optical elements: substrates, polarizers, wave plates, and so on.
Structural characteristics of Cadmium selenide powder
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.
Price of Cadmium selenide powder
