Opis

Functionalized Inorganic Fluorides: Synthesis, Characterization & Properties of Nanostructured Solids covers several classes of nanostructured and functionalized inorganic fluorides, oxide-fluorides, and fluorinated oxides such as silica and alumina. Ranging from powders or glass-ceramics to thin layers and coatings, they have applications as more efficient and less aggressive catalysts, UV absorbers, planar optical waveguides, integrated lasers and optical amplifiers, luminescent materials, anti-reflective coatings and high T_c superconductors. With a focus on new types of solids, such as nanopowders, hybrids, mesoporous fluorides, and intercalation compounds, the book covers new synthesis routes; physical-chemical characterizations - including morphology, structure, spectroscopic and optical behaviour; detailed ab initio investigations and simulations; and -last but not least- potential applications.

Inorganic fluorides and fluoride–based materials play an important role in many different applications, from silicon etching in microelectronics, isotopic enrichment of uranium in nuclear energy, to the technical revolution of fluoropolymers and fluoride coatings.

Numerous advances have been made recently through the elaboration and functionalization of inorganic fluorinated solids at the nanometre scale. Functionalized Inorganic Fluorides: Synthesis, Characterization & Properties of Nanostructured Solids covers several classes of nanostructured and functionalized inorganic fluorides, oxide–fluorides, and fluorinated oxides such as silica and alumina. Ranging from powders or glass–ceramics to thin layers and coatings, they have applications as more efficient and less aggressive catalysts, UV absorbers, planar optical waveguides, integrated lasers and optical amplifiers, luminescent materials, anti–reflective coatings and high T_c superconductors.

With a focus on new types of solids, such as nanopowders, hybrids, mesoporous fluorides, and intercalation compounds, the book covers new synthesis routes; physical–chemical characterizations – including morphology, structure, spectroscopic and optical behaviour; detailed ab initio investigations and simulations; and –last but not least– potential applications.
