“…The different duration of the current rise, depending on the metal, must be ascribed to the different chemical behavior of the metals at the interface. At present, no evidence for the formation of metallic or oxide nanoclusters can be supported by our experimental data: the shape of diffusion profiles indicates diffusion mechanism that do not involve the formation of clusters, a situation similar to those already reported for Cu and Ag migration [13,14], for which more mobile ion species (Cu + and Ag + ) do not however give rise to clusterization, at even higher temperatures in the case of Cu.…”

The use of ion-exchange techniques for doping silicate glasses with transition metals has attracted much attention in the last decades for its potential in several applications, namely, light waveguides technology, luminescent materials, and for the possibility to realize systems in which metal nanocluster formation is controlled by suitable post-exchange techniques. In this framework, the control of metal distribution inside the glass is a central issue for both the understanding of the incorporation process and for the definition of effective preparation protocols. In this experiment, metallic films (Ag, Cu, Au, Co) were deposited onto the substrates by the rf-sputtering technique. Metal ions then penetrate to substitute glass alkali by means of field-assisted ion-exchange, realized at different temperature and electric field values. In particular, we present in this paper the Au doping of silicate glasses, successfully realized for the first time with this method. The gold diffusion profiles, as measured by Secondary Ion Mass Spectrometry (SIMS), indicate that the migration depends on the experimental parameters (temperature and electric field), but also on the local structure, as well as on chemical phenomena occurring at the metal/glass interface.

“…In most of the related studies, characteristic surface-plasmon-resonance (SPR) of silver nanoparticles have always been given the maximum importance due to the fast optical response (~few psec) of nanoscale metal particles in the visible range of light [9,10]. In spite of the technological significance, precise spectroscopic studies to characterize the thermal stability of these optical nanomaterials are still only successful to a limited extent [11][12][13].…”

Results obtained from the optical absorption and photoluminescence (PL) spectroscopy experiments have shown the formation of excitons in the silver-exchanged glass samples.These findings are reported here for the first time. Further, we investigate the dramatic changes in the photoemission properties of the silver-exchanged glass samples as a function of postannealing temperature. Observed changes are thought to be due to the structural rearrangements of silver and oxygen bonding during the heat treatments of the glass matrix.In fact, photoelectron spectroscopy does reveal these chemical transformations of silverexchanged soda glass samples caused by the thermal effects of annealing in a high vacuumatmosphere. An important correlation between temperature-induced changes of the PL intensity and thermal growth of the silver nanoparticles has been established in this Letter through precise spectroscopic studies.

“…The former peak is ascribed to the spin-allowed electronic transitions from the 1 D 2 state to the ground 1 S 0 state of the Ag ions and the latter peak to the spin-forbidden electronic transition from the 3 D manifold state to the 1 S 0 state. 13 The peak intensity initially increased with increasing n from 1 to 6, then decreased with n 6 to 12, and finally the luminescence vanished at nŊ24. For samples Ag-320-n Fig.…”

The spectroscopic features of the stained glasses were examined by studying absorption, photoluminescence and electron paramagnetic resonance properties. The diffusion parameters diffusion coefficient and diffusion activation energy of silver ions were calculated based on elemental analysis data from an inductively coupled plasma ICP spectrometry, and from line scan profiles from energy dispersion X-ray analysis EDX . Key-words : Glass staining, Ion-exchange, Silver stain, Diffusion parameters, Spectroscopic properties 1. Introduction Staining is a well-known method for producing coloration in glasses.1 ,2 It is usually performed by applying a silver or copper paste to glass substrates. The substrates are then heattreated at a temperature usually lower than the glass transition temperature. In the staining process, metal ions contained in the paste replace alkaline ions present on the glass surface, and migrate inside the glass, usually followed by a redox reaction of metal ions in glass andor aggregation of metal atoms.3 ,4 These metal ions, atoms or nanoparticles exhibit one or more properties of strong visible absorption, photoluminescence and nonlinear optical response.5 -11 Therefore, staining process can be used to fabricate metal-doped glasses with applications in disk optical data storage, light waveguides, microlenses and all-optical switches. Since the first step in the staining process is the same as the process known as conventional ion exchange using molten salts, it can also be used for the study of ion diffusion properties.Previously, we have conducted a systematic investigation on silver-stained soda-lime silicate glasses.12 We found that silver was heavily doped into soda-lime silicate glass by a staining process, and that the staining process was controlled by the diffusion of silver ions in glass. The incorporated silver existed in Ag , Ag 0 and Ag
