Europium(II) telluride is an inorganic compound of europium and tellurium, with the chemical formula EuTe.
Preparation
Europium(II) telluride can be prepared by the reaction of europium and tellurium at 500–1000 °C.[3]
- Eu + Te → EuTe
The compound can also be prepared by reacting europium(II) hydride and tellurium in a stream of hydrogen at 600–850 °C:[3]
- EuH
2 + Te → EuTe + H
