Dysprosium(III) telluride is an inorganic compound, one of the tellurides of dysprosium, with the chemical formula Dy2Te3, where Dy is in the +3 oxidation state.
Preparation
Dysprosium(III) telluride can be obtained by reacting tellurium and dysprosium in a stoichiometric ratio:[1]
- 2 Dy + 3 Te → Dy
2Te
3
Properties
Dysprosium(III) telluride reacts with copper(II) telluride at high temperature to obtain phases such as DyCuTe2, DyCu5Te4, and Dy7Cu3Te12.[2] It and cadmium telluride can form CdDy2Te4 at high temperatures:[3]
- Dy
2Te
3 + CdTe → CdDy
