Inorganic nanofluorides and related nanocomposites

Charge compensation in RE3+ (RE = Eu, Gd) and M+ (M = Li, Na, K) co-doped alkaline earth nanofluorides obtained by microwave reaction with reactive ionic liquids leading to improved optical properties

“…Apart from benets arising from the large band gap, the low phonon energy, and the relatively high pyrohydrolytic stability, alkaline earth uorides are quite cheap owing to the large natural abundance of the alkaline earth salts. 1 Commonly, rare earth ions are doped into such matrices to create extrinsic luminescence. The introduction of trivalent lanthanide ions into the divalent alkaline earth uoride lattice leads to the formation of solid solutions, in which the Ln 3+ ion substitutes a M 2+ ion and the initial cubic lattice persists.…”

Non-aqueous sol–gel synthesis of nano-structured metal fluorides

Recent developments in the preparation of high surface area metal fluorides

“…Two reviews dealing with this topic appeared recently [11,23]. Review [23] gives a very broad coverage of the subject with a considerable portion devoted to various processes for the preparation of nano-sized fluorides in the pure form, as one-or two-dimensional nano-objects, or as fluoride nanocomposites. In this review, the upper limit of the nanoregion is set to 100 nm.…”
