Chemical compound
Erbium(III) selenide is an inorganic compound with a chemical formula of Er2 Se3 .
Preparation
Erbium(III) selenide can be obtained by the reaction of erbium and selenium :
2 Er + 3 Se → Er2 Se3
It can also be prepared by reacting erbium oxide and hydrogen selenide at high temperature.[3]
Er2 O3 + 3 H2 Se → Er2 Se3 + 3 H2 O
Properties
Erbium(III) selenide is an orthorhombic crystal with a Sc2 S3 structure and a space group of Fddd .[2] It reacts with magnesium selenide at 1000 °C to obtain MgEr2 Se4 .[4]
