About Zinc Telluride ZnTe Powder:
Zinc Telluride is a Group II-VI compound with the chemical formula ZnTe. In a hydrogen atmosphere, tellurium and zinc are heated together and then sublimated to produce reddish-brown zinc telluride. Because zinc telluride has a wide bandgap, it is often used to make semiconductor materials. Zinc Telluride is a semiconductor material with a direct bandgap of 2.26 eV. Usually a p-type semiconductor.
Zinc telluride usually has a cubic (galena or “zinc blende”) crystal structure, but it can also be prepared as rock salt crystals or hexagonal crystals (wurtzite structure). Under aerobic conditions, it will burn when irradiated by a strong beam. After refined by sublimation, the appearance of ZnTe is a gray or brownish-red powder or ruby red crystals. ZnTe has a lattice constant of 0.6101 nm and can be grown with or on aluminum antimonide, gallium antimonide, indium arsenide, and lead selenide. Due to certain lattice mismatches, ZnTe can also be grown on other substrates (such as GaAs) and can be grown on substrates such as glass in the form of thin-film polycrystalline (or nanocrystalline) on substrates such as glass. Thin-film solar cells. In the wurtzite (hexagonal) crystal structure, its lattice parameters a = 0.427 and c = 0.699 nm.
Zinc telluride properties
The reaction of zinc telluride with dilute acid will release highly toxic hydrogen telluride (H2Te)
Physical properties of zinc telluride
Zinc Telluride is a p-type wide bandgap semiconductor with a bandgap of 2.26eV at room temperature and 2.38eV at 77K. Feel free to send an inquiry to get the latest price if you would like to buy Zinc Telluride ZnTe Powder in bulk.

Performance of Zinc telluride ZnTe powder:
Zinc Telluride is a gray or brown-red powder, a compound of zinc and tellurium, and its chemical formula is ZnTe. Ruby red cubic crystals can be obtained by sublimation. It is stable in dry air, and decomposes in the presence of water, releasing malodorous and toxic hydrogen telluride gas. Zinc telluride is mainly used in semiconductors and infrared materials. It can be used as fluorescent materials and phosphorescent materials. It can also be used to make light-emitting diodes, as infrared detection and radiation detection materials.

How is Zinc Telluride ZnTe Powder produced?
Method 1: Seal the polycrystalline zinc telluride in a quartz ampoule with a tapered end. The Bridgman method can be used to slowly grow a single crystal of zinc telluride from the melt, in order to prevent the zinc telluride melt from sticking to the quartz container wall, Quartz ampoules must be sandblasted in advance and coated with a very thin carbon film made by pyrolysis of acetone or ethanol.
Method 2: Sodium telluride (Na2Te) and zinc acetate react in water to form a yellow-brown hydrated ZnTe precipitate.

Application of Zinc Telluride ZnTe Powder:
Zinc Telluride is a binary compound with the chemical formula ZnTe. It has the appearance of ruby-red crystals or gray or brownish-red powder. Its crystal structure is cubic, just like diamond and sphalerite. It can also be prepared as a hexagonal crystal. It is one of the common semiconductor materials.
The main use of zinc telluride is similar to that of zinc selenide. It can be used as a semiconductor and infrared material and has properties such as light guide and fluorescence.
Zinc telluride crystal has a good electro-optic effect under the action of near-infrared (~800 nm) ultrashort pulses and a mature preparation process. It is a commonly used optical rectification THz radiation source and detection material. It is used in green light-emitting devices, solar cells, waveguides and There are also applications in optoelectronic devices such as modulators.
Zinc telluride can find applications in the following areas:
LED and laser diode
Solar battery
Terahertz imaging
Electro-optical detector
Holographic interferometer
Laser optical phase conjugation device.
