“…Subsequent thermal treatment in a hydrogen atmosphere results in the formation of atoms and colloidal metal particles. Although the formation of these colloids has been documented for soda -lime silicate glasses (SLS), exchanged with Cu + ions [3,4], the spatial distributions of their size, and/or shape were not investigated in details.…”

The influence of ion -exchange conditions upon the spatial distribution of small copper particles in soda -lime silicate glasses has been investigated. The samples, polished in the shape of a wedge with a taper approximately 1 µm per 1 mm of sample length, were characterised by means of transmission electron microscopy and optical absorption spectroscopy. The observed changes of the position of the plasmon resonant band with the distance from the surface were related to the spatial distribution of the size and/or shape of colloidal copper particles. The appearance of a new optical absorption band, located on the high -energy side of the colloidal one, could be related either to some aggregates of copper or to the copper oxide colloids.

“…In this way, the oxidation could penetrate at least the surface layer. This explains why the ion exchange is promoted in the surrounding air-atmosphere, and this increase is probably responsible for the step-like penetration profile detected for the high-temperature exchange [4,7]. Hydrogenation of the exchanged specimens results in reduction of the copper ions to atoms, which coalesce with each other to form colloidal particles of metallic copper and semiconducting copper oxide.…”

“…The content of impurities (like Al, Fe, Mn and K) in these samples is slightly different from that detected previously [5]. The specimens have been exchanged (in air atmosphere) in a molten Cu 2 Cl 2 bath at 900 K for time periods between 0.17 and 6 h and subsequently annealed in gaseous hydrogen at 770 K for 5 h; for more detail see [4,7].

“…Subsequent thermal treatment of samples in air and/or hydrogen results in the formation of atoms and colloidal metal particles. Although the formation of these colloids has been recently documented for the soda lime silicate (SLS) glass exchanged with Cu + ions [3,4], effects of the glass microstructure upon the structure sensitive properties of these composites were not the subjects of detail investigations.…”

“…The composite SLSG specimens (about 10x10x1 mm 3 ) were formed by the ion exchange technique. After dipping the host matrix in a CuCl molten bath at different temperatures (720-940 K) and for different times (some minutes to 72 h), the samples were hydrogenated at 770 K for 5 h. Reduction of copper ions leads to atoms, which coalesce giving colloids of metallic copper and of semiconducting copper oxide [8]. Figure 1, left column, shows the optical absorption spectra of as prepared (a), exchanged (b) and hydrogenated (c) specimens.…”

PACS 61.43.Fs, 62.20.Mk Commercially available multicomponent soda lime silicate glass (SLSG) specimens were chemically treated in a CuCl molten bath and subsequently annealed in a hydrogen atmosphere. Mechanical properties of these specimens were monitored as function of parameters characteristic of the ion exchange process. Applying the conventional and nanoindentation techniques have determined hardness of samples. The residual stresses, induced by the dopant, were investigated by measuring the indentation cracks generated by Vickers indentation. It has been stated that although the induced increase of microhardness is not large the values of the crack formation resistance increases considerably with the increase of the dopant concentration. The results were discussed in terms of the fracture mechanics models and critically compared with those obtained previously for potassium and silver exchanged SLS glass of nearly the same chemical composition.
