Zinc Telluride Powder

Zinc Telluride Powder

Zinc Telluride powder is an inorganic compound composed of zinc and tellurium. It is a binary semiconductor material that forms a crystalline solid with a zinc blende crystal structure, similar to other group II-VI semiconductors like zinc sulfide (ZnS) and zinc selenide (ZnSe). Zinc telluride is a gray to black powder that is used in a variety of electronic, optical, and photovoltaic applications due to its useful electrical and optical properties.

Applications

Photovoltaic (Solar) Cells:

Zinc telluride is used in the production of thin-film solar cells. Its direct bandgap makes it suitable for light absorption in solar energy conversion. ZnTe is often used in combination with other materials to create thin-film solar cells that are lightweight, flexible, and cost-effective.

Infrared Detectors and Sensors:

Zinc telluride is used in the development of infrared (IR) detectors due to its ability to absorb light in the infrared region of the electromagnetic spectrum. ZnTe-based detectors are used in a variety of sensing and monitoring applications, such as in thermal imaging, gas analysis, and environmental monitoring.

ZnTe can be employed in optical sensors for the detection of gases and chemical agents, as well as in military and security systems where IR detection is essential.

Optoelectronics and Light-Emitting Diodes (LEDs):

Zinc telluride is used in the production of light-emitting diodes (LEDs) and laser diodes. Because of its direct bandgap, ZnTe can emit light when an electric current is passed through it, making it useful for optical applications.

It is used in green or blue LEDs and laser diodes that operate in the visible and near-infrared range. The material’s optical transparency and ability to emit specific wavelengths of light make it a candidate for display technology, lasers, and communication systems.

Optical Windows and Lenses:

ZnTe is used in optical windows and lenses for infrared optical systems. Its ability to transmit light in the infrared region (especially the 1-14 micron range) makes it suitable for use in thermal imaging systems, night vision technologies, and laser systems.

Zinc telluride is also used in high-power infrared lasers and other optical components that require transparent materials capable of handling high-energy photons in the infrared spectrum.
