Dysprosium(III) selenide is one of the selenides of dysprosium, with the chemical formula of Dy2Se3.




Preparation


Dysprosium(III) selenide can be prepared by reacting dysprosium(III) oxide or dysprosium(III) chloride with hydrogen selenide:

Dy2O3 + 3 H2Se → Dy2Se3 + 3 H2O
2 DyCl3 + 3 H2Se → Dy2Se3 + 6 HCl
It can also be obtained by reacting the elements at high temperatures:

2 Dy + 3 Se → Dy2Se3




Properties


Dysprosium(III) selenide reacts with arsenic triselenide to obtain DyAsSe3.

Dy2Se3 + As2Se3 → 2DyAsSe3
