Dysprosium(III) telluride

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:


 * 2 Dy + 3 Te -> Dy2Te3

Properties
Dysprosium(III) telluride reacts with copper(II) telluride at high temperature to obtain phases such as DyCuTe2, DyCu5Te4, and Dy7Cu3Te12. It and cadmium telluride can form CdDy2Te4 at high temperatures:


 * Dy2Te3 + CdTe -> CdDy2Te4
