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.
