Portaal Chemie

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.^[3]

2Er+4F_{2}\rightarrow 2ErF_{3}

Alternatiewelik kan dit ook verkry word uit erbium(III)chloried, erbiumoksied of erbiumsulfied deur dit met waterstoffluoried te laat reageer.^[4]^[5]^[6]

Erbium(III)fluoried is 'n reuklose pienk vaste stof wat in water onoplosbaar is.

Kristalstruktuur

Dit het 'n ortorombiese kristalstruktuur met die ruimtegroep Pnma (nr. 62).^[7] ^[8]Hierdie struktuur behoort tot die β-YF₃-tipe.^[2] Bo 1117 °C of by hoë druk vind 'n verandering in die kristalstruktuur plaas.^[9]^[10] Hierdie struktuur is trigonaal en behoort tot die α-UO₃-tipe (P3m1) (164).^[2]

Eienskappe

Die Er3+-ioon vertoon effektiewe luminesensie in die sigbare (blou, groen, rooi) en infrarooi gebiede (rondom 1,5 μm) van die spektrum.^[11] Dit het 'n wye bandgaping (>7 eV) en 'n lang resstraalgolflengte (>20 μm). 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.^[12]

Gebruike

Erbium(III)fluoried word as 'n dopingmateriaal (byvoorbeeld in fluoriedglase) in optiese vesels, versterkers en lasers gebruik vanweë sy sterk fluoressensie in die infrarooi gebied.^[13]^[14] Dit word ook as 'n tussenproduk gebruik om erbium te produseer.^[15]
