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 → Dy₂Te₃

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]

Dy₂Te₃ + CdTe → CdDy₂Te₄
