Description of Zinc Telluride Powder：

Zinc Telluride belongs to the Group II-VI group and has the chemical composition ZnTe. Under hydrogen atmospheric conditions, tellurium is heated with zinc and then sublimated for reddish-brown zinc telluride. It is frequently used for making semiconductor materials because of its broad bandgap. Zinc Telluride has a 2.26 eV bandgap. This is a standard p-type semiconductor.

Zinc telluride usually has a cubic structure (galena) or "zinc mixture" crystal structure. But it is also possible to make rock salt crystals, hexagonal crystals (wurtzite), and other forms. If irradiated with an intense beam, the zinc telluride will ignite under aerobic conditions. ZnTe can be refined through sublimation to form grayish or brownish-red powder or ruby-red crystals. ZnTe can grow on any combination of aluminum antimonide and gallium-antimonide, as well as indium arsenide or lead selenide. ZnTe may also develop on specific substrates, such as GaAs. ZnTe can also grown on some substrates like glass as thin-film polycrystalline. Thin-film solar panels. Its lattice parameters are a=0.427 and C =0.699 in the hexagonal wurtzite crystal structures.

Zinc telluride has properties.

Highly toxic hydrogen telluride will be produced by reacting zinc telluride and dilute acid.

ZnTe+2H+=H2Te|+Zn2+

Zinc telluride has the following physical properties

Zinc Telluride (p-type, wide bandgap semiconductor) has a bandgap value of 2.26eV at ambient temperature and 2.38eV for 77K. If you are interested in Zinc Telluride ZnTe Powder, please inquire.

Zinc telluride ZnTe powder performance

Zinc Telluride can be described as a gray-colored or reddish powder. It is composed of zinc tellurium and is chemically formulated as ZnTe. Sublimation is a way to make ruby-red cubic crystals. The cubic crystals are stable in a dry atmosphere but decompose in water. This releases the toxic, malodorous hydrogen telluride. Zinc telluride is used primarily in semiconductors. This can also be used in fluorescent and phosphorescent materials. This material can be used for light-emitting diodes and radiation detection materials.

Production Method of Zinc Telluride ZincTe Powder ：

Direct synthesis

Direct synthesis is a standard production method of zinc telluride, which directly reacts with zinc and telluride at high temperatures to obtain zinc telluride. The specific steps are as follows:

The higher purity of zinc and tellurium elements are prepared; zinc is usually present in bulk or granular form, and tellurium is generally present in powder form.

Place the zinc block or particle and tellurium powder into the quartz tube, ensuring both ends are closed.

The quartz tube is placed in a heating furnace and heated to the appropriate temperature (usually 600-800 ° C).

The high temperature is maintained for some time (e.g., several hours) to allow the zinc and tellurium to react fully.

At the end of the reaction, the quartz tube is removed, cooled, and opened to reveal the resulting zinc telluride crystals.

The advantages of direct synthesis are simple operation and easy availability of raw materials. However, it should be noted that the purity of zinc telluride 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.

Electrolysis

Electrolysis is a method of preparing compounds by electrolysis of a solution, which can be used to produce high-purity zinc telluride. The specific steps are as follows:

Dissolve an appropriate amount of zinc salts (such as zinc nitrate) and tellurium salts (such as tellurium chloride) in a solvent (such as water) to obtain a mixed solution.

The mixture is poured into the cell, and a voltage is applied to both electrodes.

During electrolysis, zinc, and tellurium ions are reduced to zinc and tellurium on the anode and deposited on the cathode to form zinc telluride.

The zinc telluride deposited on the cathode is collected for cleaning and drying.

The advantage of electrolysis is that high-purity zinc telluride can be prepared, and the cost is relatively low, which is suitable for large-scale production. However, it should be noted that the electrolysis method requires electrolytic equipment, and the operation is more complicated.

 Application of Zinc Telluride Zinc Te Powder：

Solar cell

Zinc telluride has a wide range of applications in the field of solar cells, mainly due to its excellent electrical and optical properties. Zinc telluride is a direct band-gap semiconductor material with a high absorption coefficient and low photoluminescence quenching effect, which makes it an ideal material for manufacturing efficient solar cells. In addition, zinc telluride can further improve the photoelectric conversion efficiency of solar cells through multi-band gap engineering and quantum structure design. At present, the research of zinc telluride-based solar cells has been widely concerned and has been verified in laboratory and industrial production.

Infrared detector

Zinc telluride also has essential applications in the field of infrared detectors. Because of its high electron affinity and efficient carrier transport properties, zinc telluride is widely used to manufacture long-wave and medium-wave infrared sensors. The Zinc-telluride infrared detector has high sensitivity and response speed and good thermal and chemical stability, which makes it a broad application prospect in the military, security monitoring, and environmental monitoring fields.

Optical Fiber

In optical fiber communication, zinc telluride also plays an important role. Because zinc telluride has a high refractive index and low light absorption coefficient, it is widely used to manufacture fiber core layers and coatings. By adding zinc telluride into the core layer of optical fiber, the transmission efficiency of optical fiber can be improved, and the transmission loss can be reduced. In addition, zinc telluride can also be used to manufacture optical fiber amplifiers and other optical communication devices, further expanding its application in visual fiber communication.

Other applications

In addition to the above application areas, zinc telluride has many applications in other fields. For example, it can be used as a substrate for electronic devices, manufacture optoelectronic devices such as light-emitting diodes and lasers, prepare large-size single-crystal materials, and manufacture high-temperature superconducting materials. These applications further expand the scope of zinc telluride applications in materials science and engineering.
