Zinc Selenide ZnSe Powder
Zinc Selenide (Zinc Selenide), an inorganic compound, has the molecular structure ZnSe with a molecularweight of 144.35. It comes in a yellow cubic crystal form. The relative density is 5.65. Sublimation. Transmittance is greater than 60% for infrared lights with wavelengths below 15 mm. You can see light rapidly turning red, long-term in the air, or easy decomposition in the case dilute nitric. Zinc selenide, while insoluble in water and reacts with acids to create toxic hydrogen selenide gaz.
Zinc selenide is made of zinc (Zn), and selenium. This intrinsic semiconductor has an energy bandgap at about 2.70eV (77degF) at 25degC.
ZnSe can be described as a broadband semiconductor belonging to the IIVI semiconductor family. It is difficult but possible. P-type doping, however, is easier and can be done by adding gallium.
Zinc selenide consists of selenium, zinc II – VI compound semiconductor material materials. If heated to a temperature in the atmosphere, they will become carbon dioxide selenium or zinc oxide. Their forbidden bandwidth is 2.6eV. The compound semiconductor is capable of emitting visible light in all colors except blue.

Zinc Selenide ZnSe Powder
produced?
Zinc selenide may be made by heating ZnSO4 solution and H2Se, or ZnO and ZnS together and heating them to 800. This is an organic catalyst to make acetone by converting itopropanol into acetone. A Phosphor is an organic compound which contains Cd but has a low amount of Zn.
1. A dilute solution of zinc sulfurate, buffered by ammoniumacetate, is added into the saturated H2Se solution. H2Se gas is then diluted or added to this solution. Heat the precipitated vessel in a steambath. After that, add H2Se gas diluted with N2 or H2 to the solution. Zinc salt solutions that are too concentrated or too quickly introduced will cause white precipitates. These precipitates will not change into yellow ZnSe and will need to be removed by centrifugation. After the separation, it was first washed in boiled ammonia then again with methanol. After the ZnSe precipitates had been cleaned, they were dried first in a vacuum dryer with CaCl2. Next, it was dried at 120° C in a dryer with P2O5.
Zinc selenide reacts very strongly to moisture. The dried product should be placed inside a glass tube and heated to 600 °C in H2 or Se atmosphere for 2 4 hours to get rid of the oxidization.
2. The mixture of four grams zinc oxide, two-thirds of a cup zinc sulfide, and six grams selenium were placed inside a quartz crucible with the lid. After heating at 800 for 15 mins to get the ZnSe product, the mixture was removed from the crucible and heated again.
Applicaciones
Zinc Selenide ZnSe Powder
ZnSe is produced in melt with excess inert gases pressure (usually Ar). ZnSe is ideal for use in 10.6 mm wavelength CO2 laser optics as it does not absorb or include any inclusions. ZnSe therefore is an infrared important material. ZnSe has an extremely wide transmission wavelength range (between 0.45 and 21.5mm). Green had a refractive value of 550nm, while the LWIR refractive index was at 10.6mm. ZnSe can also be used for:
1. ZnSe is a good choice for both fluorescent materials and semiconductor dopants.
2. ZnSe has a wide range of uses in medicine, laser, and infrared.
3. Znse is used in the manufacture of infrared transmissible materials and optical instruments
4. ZnSe is used for the formation of an IIVI LED and diode-laser. It emits blue light.
Infrared laser gain medium for Cr Doped ZnSe, (ZnSe : Cr), has an emission wavelength approximately 2.4 mm.
5. A scintillator with 640nm wavelength, called Activated ZnSe (ZnSe(TE),) which can be used to match the photodiode’s light intensity is known as ZnSe. This scintillator is useful for X and gamma radiation detectors. ZnSe scintillator has a distinct design.
