Dysprosium selenide is one of the selenides of dysprosium, with the chemical formula of Dy₂Se₃. It can be prepared by reacting dysprosium(III) oxide or dysprosium(III) chloride with hydrogen selenide,[1] or by reacting the elements at high temperatures.[2] It reacts with arsenic triselenide to obtain DyAsSe₃.[3]
