How is Zinc Selenide ZnSe Powder produced?
Zinc selenide can be prepared by the reaction of H2Se with ZnSO4 solution, or by the reaction of ZnO, ZnS and Se mixed and heated to 800 ℃. Used as a catalyst for the organic synthesis of acetone from isopropanol. A compound containing Cd with a small amount Of Zn is Called a Phosphor.
1. Dilute solution of zinc sulfate buffered with ammonium acetate is added to the saturated solution of H2Se, and H2Se gas diluted with N2 or H2 is added to the solution (formed by the reaction of Al2Se3 and dilute hydrochloric acid) . The precipitated vessel is heated over a steam bath and the excess H2Se gas is absorbed in a wash bottle containing concentrated nitric acid. If the zinc salt solution is introduced too fast or the concentration is too high, the white precipitate will be formed, and it will take a long time to change to the yellow ZnSe.Yellow ZnSe precipitates are difficult to filter and need to be separated by centrifugation. The separated precipitate was washed first with boiled dilute ammonia and then with methanol. The cleaned ZnSe precipitates were first dried in a vacuum dryer containing CaCl2.Then, It was dried in a dryer containing P2O5 AT 120 ° C.
Zinc selenide is very sensitive to air when it is wet. Therefore, the dried product needs to be placed in the glass tube, heated at 600 ℃, H2 or H2Se atmosphere for 2 ~ 4h, to remove the oxidized product.
2. A mixture of 4g zinc oxide, 2.5g zinc sulfide and 6g selenium was placed in a quartz crucible in the lid and heated at 800℃ for 15 minutes to obtain the ZnSe product.
Applications of Zinc Selenide ZnSe Powder:
ZnSe is grown in melt under excess inert gas pressure (usually Ar). When there is no absorption and inclusions, it is very suitable for 10.6 μm wavelength CO2 laser optics. Therefore, ZnSe is a very important infrared material. It has a very wide transmission wavelength range (0.45 ~ 21.5 μm). The refractive index of 550 nm (green) and 2.40 refractive index was 10.6 μm (LWIR). In addition, ZnSe applications include:
1. ZnSe can be used as a fluorescent material and a semiconductor dopant;
2. ZnSe is widely used in laser, medicine, astronomy and infrared fields.
3. Znse is used to make infrared transmitted materials and infrared optical instruments
4. ZnSe is used to form an II-Vi LED and diode laser. It produces blue light.
Cr Doped ZnSe (ZnSe: Cr) is used as an infrared laser gain medium with an emission wavelength of about 2.4 μm.
5. Activated ZnSe (ZnSe (TE)) is a scintillator having 640 nm, which is suitable for matching the photodiode. It is used for X-rays and gamma-ray detectors. The ZnSe scintillator is obviously different from the ZnS scintillator.

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. Tqhp is a trusted global Cadmium Selenide CdSe Powder supplier.

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:
Optoelectronic devices
Laser diode
Biomedical imaging
Nanosensing

About Gallium Selenide Ga2Se3 Powder:
Gallium(III) Selenide is a compound. It has a hexagonal layered structure, similar to a gas. It is a photoconductor, a second harmonic crystal in nonlinear optics, and is used as a far-infrared conversion material for terahertz and above.
Gallium(III) Selenide has a defective sphalerite (cubic ZnS) structure. It is a p-type semiconductor.Gallium(III) Selenide(III) can be formed by combining elements. It reacts slowly in water and rapidly in inorganic acids, forming toxic hydrogen selenide gas. The reducing power of selenium ions makes them susceptible to oxidizing agents. Therefore, it is advised not to contact the base.
As a nonlinear optical material and photoconductor, Gallium(III) Selenide crystals have great prospects for development. Nonlinear optical materials are used for the frequency conversion of lasers. Frequency conversion involves changing the wavelength of a monochromatic light source (usually a laser) to a higher or lower wavelength of light that cannot be produced by a conventional laser source.Tqhp is a trusted global Gallium Selenide Ga2Se3 Powder supplier. Feel free to send an inquiry about the latest price of Iron Gallium Selenide at any time.
There are several methods for frequency conversion using nonlinear optical materials. The generation of the second harmonic causes the frequency of the infrared carbon dioxide laser to double. In optical parameter generation, the wavelength of light is doubled. Near-infrared solid-state lasers are usually used for optical parameter generation
One of the original problems with using the Gallium(III) Selenide in optics is that it easily breaks along the cleavage lines and is therefore difficult to cut in practical applications. However, it has been found that the doping of indium in crystals greatly improves their structural strength, making them more practical for application. However, there are still some difficulties that must be overcome in crystal growth before Gallium(III) Selenide crystals may be used more widely in the field of optics.

About Calcium Nitride Ca3N2 powder
In most cases, calcium nitride is usually available in large volumes. Tqhp provides a wide range of products for hydrogen storage research, advanced fuel cells, and battery applications. Hydrogen is easily produced from renewable energy sources and is the most abundant element in the universe. Hydrogen comes from many sources, such as solid fuels, water, and renewable materials. Hydrogen is non-polluting and will form harmless water during use. Challenges related to the use of hydrogen as an energy source include the development of safe, compact, reliable, and cost-effective hydrogen storage and transmission technology. Currently, hydrogen can be stored in three forms: compressed hydrogen, liquid hydrogen, and chemical storage. High purity, submicron and Nanopowder forms can be considered. Calcium nitride is the main raw material for high-end phosphors. This phosphor is more stable, has better performance, and has better effects at high temperature and high humidity. Last but not least, calcium nitride can also be used as a chemical treatment agent, which is the key to determining the performance of water-based mud. Feel free to send an inquiry to get the latest price if you would like to buy Calcium nitride in bulk.
How is Calcium Nitride Produced?
When calcium burns in the air, it forms Ca3N2 with the oxide CaO. The distilled fibrous metallic calcium is heated to 450°C in a purified nitrogen stream, and then the metallic calcium is nitrided into calcium nitride after 3-4 hours.
Depending on the preparation temperature, the obtained calcium nitride is black at 350°C, milky white at 350 to 1150°C, or golden yellow at 1150°C or higher. It is easy to identify the calcium nitride formed because it can react with moisture or water and produce calcium hydroxide and ammonia.
Applications of Calcium Nitride
Ca3N2 can be used for obtaining reactive nitride ions, Calcium hydride (a desiccant) can be produced by heating calcium nitride with hydrogen at temperatures above 350 °C.
