Holmium selenide

Holmium selenide is an inorganic compound with the chemical formula Ho2Se3. It can be obtained from the reaction of holmium and selenium (in the presence of iodine[2]) or holmium oxide and hydrogen selenide at high temperature.[3] It can form orthorhombic AgHoSe2 in the binary system of silver selenide.[4]
