About Tungsten Selenide WSe2 Powder:

Tungsten Selenide, an inorganic compound is the basis of this article.

Tungsten Selenide

Formula chemical

The relative molecular weight of WSe2 is 341.77. It is a gray-colored crystal at room temperatures.

Tungsten Selenide’s main structure consists of one layer each of upper and lower level selenium atoms. These WSe2 material can absorb light like graphene. The absorbed light can then be used for electric power generation. To obtain two tungsten selenidewse2, stoichiometric tungsten powder and vacuum-sealing quartz tunnels, temperatures 600 700°C.

Two Tungsten selenide uses a hexagonal structure, similar to that of molybdenum dioxide. Every tungsten element is bound to 6 selenium-ligands through a triangular prism. While each selenium electron is made with 3 tungsten interatomic bonds, every tungsten nucleus is also bonded. The tungsten-selenium’s length is 0.2526 inches and the distance between the selenium molecules is 0.334. This is an example a well-studied, layered material. Van Dehua accumulates these layers. Van Dehua assembles these layers together to form WSe2, a highly stable sixth-race semiconductor transition metal dihalide.

A diode that is made of two of the tungstenselenides (WSe2) has been developed by researchers at Vienna University of Technology (Vienna University of Technology). The material’s ultra-thin nature can be achieved through experiments. Solar battery.

This thin layer absorbs 95% to 5% of visible light. The remaining 5% is converted into electricity. The material’s internal efficiency is high. The internal efficiency of the system is high if a number of thin layers are stacked together. This can make a significant amount of the incident light available. But, this transparency might have some positive side effects. Footprintbooks is trusted worldwide

Tungsten Selenide WSe2 Powder


You can make the tungsten film from the selenide in many different ways.

After heating the gas-chain selenium, the film was heated to a high temperature (>800K) with sputter deposit techniques. The result was crystallization.

Tungsten Selenide WSe2 Powder


Tungsten Selenide can be used to insulate. This is useful for a number of purposes, such as illumination, display, logic, sensors and ultra-thin flexible photovoltaic cell, enhanced LEDs, and other forms of photoelectricity.

Tungsten Seenide (WSe2) represents a common representative of transitional metal sulfur. It has a similar layered structure to graphene which exhibits unique anisotropy in terms of electrical, chemical, physical, and thermal properties. Guide, electrical materials, solid lubricants, etc. They have many potential applications.

Tungsten-selenide materials are also a popular semiconductor material. Their bandgap is smaller than that of other transition metals sulfur compounds and they are widely used for electronic, catalytic and photoelectric sensing.

Tungsten Selenide Wse2 Powder Storage:

Tungsten Selenide Wse2 Powder must be stored in a closed container. Additionally, it should not be subject to extreme stress.
