Summary

Many recent research advances in inorganic fluorinated solids have come about as a result of the elaboration and functionalization of these materials at the nanometric scale. The book will cover several classes of nanostructured and functionalised inorganic fluoride-based solids, including powders, glass-ceramics, thin layers, nanotubes for applications as catalysts, inorganic charges, coloured pigments, UV absorbers, phosphors, and materials for integrated optics.Topics covered range from new synthesis routes to physico-chemical characterizations concerning decisive properties of these materials, including morphology, diffraction, thermal, spectroscopic and optical behaviour. A strong focus will be on new types of solids such as nanopowders, hybrids, mesoporous and intercalated fluorinated materials. The theoretical approach of the subject and the potential applications will be also highlighted.
