Preparation
editLutetium(III) selenide can be obtained by reacting lutetium and selenium:
- 2 Lu + 3 Se → Lu2Se3
It can also be prepared by reacting lutetium oxide and hydrogen selenide at a high temperature:[2]
- Lu2O3 + 3 H2Se → Lu2Se3 + 3 H2O
Properties
editLutetium(III) selenide can form orthorhombic AgLuSe2 in the binary system of silver selenide.[3] It can form Lu2PbSe4 and Lu2Pb4Se7 in the binary system of lead selenide.[4]
