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 → Lu₂Se₃

It can also be prepared by reacting lutetium oxide and hydrogen selenide at a high temperature:

Lu₂O₃ + 3 H₂Se → Lu₂Se₃ + 3 H₂O

Properties

Lutetium(III) selenide can form orthorhombic AgLuSe₂ in the binary system of silver selenide. It can form Lu₂PbSe₄ and Lu₂Pb₄Se₇ in the binary system of lead selenide.
