Rare Earth Fluoride

Fluoride refers to organic or inorganic compounds containing negative fluorine. Like other halogens, fluorine forms a single negative anion (f −). Fluorine can form binary compounds with all elements except He, Ne and Ar. Rare earth fluoride refers to the compound composed of fluorine and rare earth metal elements. The common rare earth fluoride are LaF3, CeF3, PrF3, NdF3, GdF3, DyF3, YF3, etc. It can be used in biochemical research, yttrium salt, fireworks, precipitant, infrared low refractive index materials, laser crystal materials, up conversion luminescence materials and so on.
