General description
Tellurium is anon-radioactive and heaviest member of the chalcogen family. It has a widerange of oxidation states, from -2 to +6. It is widely used in the fields ofmetallurgy and electronics.
Application
Tellurium can be used as a precursor to prepare:
- Tellurium-based nanomaterials for semiconductor application, such as CdTe nanoparticles via solvothermal synthesis.
- Quantum dot solutions for fluorometric determination of bioactive compounds.
- Thermoelectricmaterials, such as Cu4Mn2Te4 by the melting-quenching-SPS method.
Tellurium, in combination with potassium hydroxide, mediates the quantitative pinacolization of aromatic carbonyl compounds.

The present work describes synthesis of water soluble L-cysteine-functionalized CdTe quantum dots (QDs) with size tunable emission at different time intervals for chitosan based film. The characterization of the synthesized CdTe QDs-chitosan film was made by Fourier transform infrared (FTIR)

Despite being disparaged for their malodorous and toxic demeanour, compounds of selenium, a bio-essential element, and tellurium, offer possibilities as therapeutic agents. Herein, their potential use as drugs, for example, as anti-viral, anti-microbial, anti-inflammatory agents, etc., will be surveyed along
