Description of Zinc Selenide ZnSe Powder:
Zinc Selenide (Zinc Selenide), an inorganic compound, has the molecular structure ZnSe with a molecular weight 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 light wavelengths below 15mm. You can see the light rapidly turning red when the wavelength is less than 15 mm. Zinc selenide, while insoluble in water, reacts with acids to create toxic hydrogen selenide gas.
Zinc selenide is made of zinc (Zn) and selenium. It's an intrinsic semiconductor with a bandgap at 25degC (77.5degF) of approximately 2.70eV.
ZnSe can be described as a broadband semiconductor belonging to the IIVI family. It is difficult but possible. P-type doping, however, is more accessible 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 can emit visible light in all colors except blue. If you are interested in Zinc Selenide ZnSe Powder, please inquire.
Zinc Selenide ZnSe Pulp - Properties Zinc selenide, with the chemical formula ZnSe, has a molecular weight 144.33. This solid, light-colored compound is insoluble when dissolved in water. You can make it by reacting with zinc chloride or zinc sulfate. With hydrogen selenide. Useful in laser medicine, astronomy, night vision, and other fields. A yellow transparent, polycrystalline zinc selenide substance has a crystal size of 70 mm. It also has a light transmission range between 0.5-15 mm. The chemical vapor deposit (CVD) method has zero impurity absorption and a shallow scattering loss. This material is the best choice for making optical devices using high-power CO2 lasers because of its low absorption at 10.6mm wavelength. Additionally, this material is used frequently in other optical systems throughout its light transmission spectrum.

Production Method of Zinc Selenide ZnSe Powder:Direct synthesis
Direct synthesis is a standard method for the production of zinc selenide. Zinc selenide is obtained by immediately reacting zinc and selenium at high temperatures. The specific steps are as follows:
The higher purity of zinc and selenium elements are prepared. Zinc is usually present in powder form, and selenium is generally present in gas or liquid form.
Zinc powder and selenium elements are placed in a high-temperature furnace and heated to the appropriate temperature (usually 800-1000 ° C).
Keep the temperature high (e.g., several hours) to allow the zinc and selenium to react fully.
After the reaction, the furnace is cooled, and the resulting zinc selenide is removed.
The advantages of direct synthesis are simple operation and easy availability of raw materials. However, it should be noted that the purity of zinc selenide obtained by this method may need to be higher, and further purification is required. In addition, the direct synthesis method has a higher cost and is unsuitable for mass production.
Chemical vapor deposition
Chemical vapor deposition is a method for the preparation of zinc selenide. The volatile compounds of zinc and selenium are reacted in the gas phase and deposited on the substrate to obtain zinc selenide. The specific steps are as follows:
Volatile compounds of zinc and selenium (such as zinc chloride, selenite, etc.) are heated to high temperatures to evaporate into gases.
The gas is passed into the reaction chamber, mixed with hydrogen or argon, and deposited on the substrate (such as silicon, glass, etc.) to obtain zinc selenide.
After the deposition, the substrate was removed, and the zinc selenide film was obtained.
The advantage of CVD is that high-purity zinc selenide films can be prepared, and the thickness and properties of the movie can be controlled by controlling reaction conditions and substrate temperature. In addition, chemical vapor deposition can also deposit zinc selenide films on complex shapes of objects, such as optical fibers, microelectronic devices, etc. However, it should be noted that the equipment of the chemical vapor deposition method has a high cost and requires professional technical personnel to operate and maintain.
Solvothermal method
The solothermic method is a method to prepare zinc selenide, which dissolves zinc and selenium salts in a solvent (such as alcohol, amide, etc.) and then reacts under a specific temperature and pressure to obtain zinc selenide. The detailed steps are as follows:
The salts of zinc and selenium (such as zinc chloride, selenite, etc.) are dissolved in a solvent to form a homogeneous solution.
The solution is transferred to a high-pressure reactor, heated to a specific temperature (usually between 100-200 ° C), and pressurized (e.g., several atmospheres).
Reacting at a specific temperature and pressure for some time (for example, several hours), zinc and selenium react in a solvent to obtain zinc selenide.
After the reaction, the high-pressure reactor is cooled to room temperature, and the resulting zinc selenide is removed.
The advantage of the solvothermal method is that high-purity zinc selenide can be prepared, and the particle size and morphology of the product can be controlled by controlling the reaction conditions. In addition, the solvothermal method can also use different types of solvents and additives to prepare other properties of zinc selenide materials. However, it should be noted that the reaction conditions of the solvothermal method are harsh, requiring high-pressure reactors and high-temperature conditions, so professional technicians are required to operate and maintain them.
