Lutetium(III) selenide is an inorganic compound with the chemical formula Lu2Se3.
Preparation
Lutetium(III) selenide can be obtained by reacting lutetium and selenium:
- 2 Lu + 3 Se → Lu
2Se
3
It can also be prepared by reacting lutetium oxide and hydrogen selenide at a high temperature:[1]
- Lu
2O
3 + 3 H
2Se → Lu
2Se
3 + 3 H
2O
Properties
Lutetium(III) selenide can form orthorhombic AgLuSe2 in the binary system of silver selenide.[2] It can form Lu2PbSe4 and Lu2Pb4Se7 in the binary system of lead selenide.[3]
