“…However, applications of nan-oclusters have a much older history, and here we would like only to mention a striking example which dates to several centuries ago. In fact, it has been recently discovered (Borgia et al, 2002;Padeletti and Fermo, 2003) that the Renaissance masters in Umbria, Italy, used nanoparticles in the decoration of majolicas with lustre. Lustre consists of a thin film containing silver and copper clusters with diameters up to a few tens of nanometers, and often of non-crystalline structure.…”

The structural properties of free nanoclusters are reviewed. Special attention is paid to the interplay of energetic, thermodynamic and kinetic factors in the explanation of the clusters structures which are actually observed in the experiments. The review starts with a brief summary of the experimental methods for the production of free nanoclusters, and then proceeds with a guideline given by theoretical and simulation issues, always discussed in close connection with the experimental results. The energetic properties are treated first, evidencing general trends, describing the methods for modelling the interactions between the elementary cluster constituents, and for the global optimization on the cluster potential energy surface. After that, a chapter on cluster thermodynamics follows. The discussion includes the analysis of solid-solid structural transitions, and of melting with its size dependence. The last part is devoted to the growth kinetics of free nanoclusters, and treats the growth of isolated clusters and their coalescence. Several specific systems are analyzed.

“…The most remarkable feature of these materials is their high specular reflectance conveying to them metal-like appearance. [1][2][3][4] Although all this may suggest a product of modern nanotechnology and engineering, the fact is that the first lusters were obtained as early as 9th century A.D. in the Abbasid caliphate. 5,6 Several studies have shown that the lusters consist of a thin surface layer (several hundred nanometers thick) of metal nanoparticles, silver and/or copper with sizes ranging between 2 and 50 nm, randomly distributed within a glassy matrix.…”

“…5,6 Several studies have shown that the lusters consist of a thin surface layer (several hundred nanometers thick) of metal nanoparticles, silver and/or copper with sizes ranging between 2 and 50 nm, randomly distributed within a glassy matrix. [1][2][3][4] The production process [7][8][9] involves first ion exchange between the silver/copper ions (Ag þ /Cu 2þ or Cu þ ) from an initial mixture applied on the glass surface and the alkaline (Na þ and K þ ) ions from the glass, and then the nucleation and growth of metal nanoparticles through reduction of Ag þ to Ag 0 and Cu 2þ /Cu þ to Cu 0 .…”

Lusters are composite thin layers of coinage metal nanoparticles in glass displaying peculiar optical properties and obtained by a process involving ionic exchange, diffusion, and crystallization. In particular, the origin of the high reflectance (golden-shine) shown by those layers has been subject of some discussion. It has been attributed to either the presence of larger particles, thinner multiple layers or higher volume fraction of nanoparticles. The object of this paper is to clarify this for which a set of laboratory designed lusters are analysed by Rutherford backscattering spectroscopy, transmission electron microscopy, x-ray diffraction, and ultraviolet-visible spectroscopy. Model calculations and numerical simulations using the finite difference time domain method were also performed to evaluate the optical properties. Finally, the correlation between synthesis conditions, nanostructure, and optical properties is obtained for these materials. V C 2012 American Institute of Physics. [http://dx

“…It is this technique which allowed for the first observation of nanocrystals in an archaeological lustre, a 13 th century lustre of Hispano-Moorish period (Pérez-Arantegui, Molera et al 2001). Although it is an abrasive technique, which is an obstacle for the investigation of museum pieces, several specimens from different periods and different geographic areas have been analysed by TEM (Borgia et al 2002;Padeletti & Fermo 2003b;Pérez-Arantegui & Larrea 2003;Fredrickx et al 2004;Padeletti & Fermo 2004;Roqué et al 2007;Mirguet et al 2008;Mirguet, Roucau et al 2009;Sciau et al 2009a). For some of them, sampling was limited to a few thousand cubic micrometres, using focused ion beam (FIB) techniques (Sciau et al 2009b).…”
