High Purity Zinc Selenide ZnSe Powder CAS 1315-09-9, 99.9% |

Zinc selenide’s chemical formula is ZnSe. Its molecular weight is 144.33. It is an insoluble solid compound, which is light yellow. It is produced by reacting zinc sulfate or zinc chloride. With hydrogen selenide. It is widely used in the areas of lasers, medicine and astronomy. The zinc selenide polycrystalline material is yellow and transparent with crystal particles of approximately 70 mm. Light transmission ranges from 0.5-15mm. Chemical vapor deposit (CVD), on the other hand, has virtually no impurity-absorption and a very low scattering. Due to its small absorption for light of 10.6mm, it is now the material of preference in the production of optical components within high-power laser systems. It is also widely used across the entire spectrum of its light transmission in different optical systems.

What is Zinc Selenide ZnSe Powder produced?
Zinc selenide may be produced by the reaction between H2Se in a ZnSO4-solution and ZnO or ZnO and ZnS mixed with Se heated to 800. Catalyst for the synthesis of isopropanol into acetone. A Phosphor compound is one that contains Cd along with a tiny amount of Zn.
1. A diluted solution of zincsulfate buffered by ammonium acetate, is added to a saturated solution of hydrogen sulfide. H2Se is then added diluted with H2 or N2 to the solution. The precipitated vessel will be heated on a steam bed and the excess gas of H2Se will be absorbed by a wash-bottle containing concentrated Nitric Acid. The zinc salt solution will form a white precipitate if it is added too fast, or if its concentration is high. It takes a long while for this to change into yellow ZnSe. The separated precipitate has been washed twice with ammonia dilute boiled and then with Methanol. The ZnSe precipitates cleaned were dried in an vacuum dryer with CaCl2.
Zinc selenide is extremely sensitive to air when wet. To remove the oxidized products, the dried product should be placed into the glass tube and heated to 600°C, H2Se or H2Se for 24 hours.
2. To obtain ZnSe, a mixture of 6g selenium, 2.5g zinc sulfide, and 4g zinc oxide was placed into a quartz lid in the crucible and heated to 800 degrees Fahrenheit for 15 min.

Applications Zinc Selenide ZnSe Powder
ZnSe melt is grown under excessive inert gas pressure, usually Ar. If there is no inclusions and absorption, this material is perfect for CO2 Laser Optics with 10.6 mm wavelength. ZnSe has a high infrared transmission wavelength range. It transmits light in a wide range of wavelengths (0.45 to 21.5mm). The refractive Index of 550nm was 10.6mm for LWIR and 2.40 refractiveindex was 10.6mm for green. ZnSe also has applications in:
1. ZnSe is a fluorescent and semiconductor dopant.
2. ZnSe can be found in many fields, including lasers, medicine, astronomy, infrared and astronomy.
3. Znse used in the manufacture of infrared transmission materials and infrared-optical instruments
4. ZnSe can also be used in the formation of diode lasers and II-Vi leds. It produces a blue light.
Infrared laser gain mediums with a wavelength of 2.4mm are made from ZnSe doped with Cr.
5. The scintillator ZnSe(TE) has a wavelength of 640 nm and is suitable to match a photodiode. It can be used to make X-rays or gamma rays detectors. The ZnSe Scintillator differs from the ZnSe Scintillator.
