1947 J. K. Marsh in Q. Rev. Chem. Soc. 1 126 The term ‘lanthanon’ (Ln) is proposed to denote any element of the group from lanthanum to lutecium inclusive and to replace such objectionable terms as ‘lanthanate’ or ‘lanthanide’ which have recently had some currency.

1951 Nature 31 Mar. 526/1 An analysis of the lanthanon (rare earth) fraction from davidite..has revealed an unusual variation in the abundance of the lanthanons.

1961 W. K. Anderson in Spedding & Daane Rare Earths xxii. 522 Advances in the technology and availability of the lanthanons..have brought about an upsurge of interest among nuclear technologists.

1973 Jrnl. Chromatogr. 76 459 Sym.-EDDA was studied..as a complexant for the trivalent lanthanons and yttrium.
