Abstract

The lanthanide metaborates LnB₃O₆ contain chains of composition ${\left[{\text{B}}_6{\text{O}}_{12}\right]}_{\infty }^{6-}$ which are linked together by the lanthanide ions. These ions are situated in a distorted ten-cornered polyhedron. These polyhedra, linked together by their common oxygen edges, form infinite layers (1). The shortest Ln-Ln distance is about 4 Å. Here we wish to report that these compounds are excellent host lattices for efficient luminescent materials.
