Erbium selenide is an inorganic compound with a chemical formula of Er₂Se₃. It is an orthorhombic crystal with a Sc₂S₃ structure and a space group of Fddd.^[2] It can be obtained by the reaction of erbium and selenium or erbium oxide and hydrogen selenide at high temperature.^[3] It reacts with magnesium selenide at 1000 °C to obtain MgEr₂Se₄.^[4]
