In this paper, a new class of NH 4 Ln 2 F 7 (Ln = Y, Ho, Er, Tm, Yb, Lu) inorganic nanocages that has been discovered will be presented. A facile template‐free synthetic route was developed for one step, high yield, and large scale synthesis of ternary NH 4 Ln 2 F 7 (Ln = Y, Ho, Er, Tm, Yb, Lu) nanocages. On the basis of our studies, these nanocages are thermodynamically stable forms of this group of NH 4 Ln 2 F 7 compounds. The tendency of NH 4 Ln 2 F 7 (Ln = Y, Ho, Er, Tm, Yb, Lu) to form these new‐type nanostructures is believed to have a close relationship with their inherent layered structures, similar to that of inorganic fullerene‐like nanoparticles. This new type of nanocage can be easily doped with other lanthanide ions, which may endow these nanocages with novel properties. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
