Abstract
A rare earth compound including: one or a plurality of rare earth ions; and a ligand coordinated with the rare earth ion and having a condensed polycyclic aromatic group. At least part of the rare earth ions is a terbium(III) ion. The condensed polycyclic aromatic group is a residue formed by removing a hydrogen atom bonded to a condensed aromatic ring in formula (1) below from a condensed polycyclic aromatic compound represented by the following formula (1). Also disclosed is a luminescent body including the rare earth compound.
