Erbium(III) fluoride is the fluoride of erbium, a rare earth metal, with the chemical formula ErF₃. It can be used to make infrared light-transmitting materials ^[3] and up-converting luminescent materials. ^[4]

Production

Erbium(III) fluoride can be produced by reacting erbium(III) nitrate and ammonium fluoride: ^[5]

Er(NO₃)₃ + 3 NH₄F → 3 NH₄NO₃ + ErF₃
