Rare-earth element | Uses, Properties, & Facts | Britannica
Collectively, the rare earths rank as the 22nd most abundant "element" (at the 68th percentile mark). The non- lanthanide rare-earth elements, yttrium and scandium, are 29th and 44th, respectively, in their abundances. Lanthanum and the light lanthanides (cerium through europium) are more abundant than the heavy lanthanides ( gadolinium ...
Rare Earth, Rare Earth Luminescence, Luminescent Rare Earth …
The incompletely filled 4f shell of rare earth ions possesses single electrons and produces the non-zero spin quantum number (S). So the spin angular momentum splits and disturbs the orbital angular momentum (L) in the same space region, resulting in the fine splitting of orbital energy levels, so-called the spin–orbit coupling e ffect.
