'''Erbium(III)fluoried''' is 'n anorganiese chemiese verbinding van [[erbium]] met [[fluoor]].

Erbium(III)fluoried kan verkry word deur erbium met fluoor te laat reageer.<ref name="chemical reaction data">chemical reaction data: [http://www.webelements.com/erbium/chemistry.html WebElements Periodic Table of the Elements | Erbium | chemical reaction data]</ref>
:<math> 2Er+ 4F_2 \rightarrow 2ErF_3</math>

Alternatiewelik kan dit ook verkry word uit erbium(III)chloried, erbiumoksied of erbiumsulfied deur dit met [[waterstoffluoried]] te laat reageer.<ref name="J.

==Eienskappe==
Die Er3+-ioon vertoon effektiewe luminesensie in die sigbare (blou, groen, rooi) en [[infrarooi]] gebiede (rondom 1,5 μm) van die spektrum.<ref>{{cite journal |authors=O. B. Petrova, M. N.

Dit is deursigtig van die diep [[ultraviolet]] tot die langgolf infrarooi. Hierdie eienskappe maak dit 'n belowende optiese materiaal. Die afsnygolflengte van erbiumfluoried-bevattende fluoriedglas in die infrarooi kan 21 μm bereik, wat beteken dat dit as 'n infrarooideurlatende materiaal gebruik kan word.<ref>{{cite journal |authors=W.

==Gebruike==
Erbium(III)fluoried word as 'n dopingmateriaal (byvoorbeeld in fluoriedglase) in [[optiese vesel]]s, versterkers en lasers gebruik vanweë sy sterk [[fluoressensie]] in die infrarooi gebied.<ref>{{cite web |url=https://www.nanorh.com/product/erbium-fluoride-powder/ |title=Erbium Fluoride Powder - Nanorh |publisher=nanorh.com}}</ref><ref>{{cite journal|authors=W.
