    Small silver particles in glass surface layers produced by sodium-silver ion exchange — their concentration and size depth profile (1991)

    Notes: Abstract Small spherical silver particles in a surface layer of commercial flat glass were produced by means of sodium-silver ion exchange. In each volume element of the layer there is a Gaussian distribution of the particle diameters. The mean diameter increases with penetration depth. Within one individual sample it can vary from 4.5 nm immediately at the glass surface up to more than 50 nm at the end of the layer. Due to a special preparation technique the results were gained by microspectrophotometric measurements as well as by investigations carried out with the transmission electron microscope and the electron-probe microanalyzer on one and the same sample always as function of the penetration depth.

    Aggregates of small silver particles in surface layers of glasses — electron microscopy and optical microspectroscopy (1991)

    Notes: Abstract In glasses containing antimony or arsenic in the order of 1 weight-% the treatment with a silver-containing paste yields a dark-red surface layer. Transmission electron microscopy shows that there are aggregates of spherical silver particles in the coloured layer. Optical microspectroscopy proves extinction spectra consisting of two bands. Comparing these spectra with calculated ones reveals that the two bands can be explained by the existence of aggregates. The change of the extinction within the coloured layer is a result of the mutually different spatial arrangements of the silver particles which were found by electron microscopy.

    Notes: Abstract: The size evolution of the surface plasmon resonance was investigated for free and embedded silver particles between about 2 to 10 nm in size. The crystal lattice of such particles as analyzed by high resolution electron microscopy show linear contraction with reciprocal particle size. Based on this, a model was presented by combining the lattice contraction of particles and the free path effect of electrons to predict the size evolution of the resonance. The results reveal a contribution of the lattice contraction to the resonance shift according to a roughly linear relation that changes slightly with particle radius (〉 1.0 nm) and surrounding media. This surface plasmon resonance shift proceeds linearly with reciprocal size for Ag particles in vacuum and argon, but for Ag particles embedded in glass it appears to be independent of the radius down to nearly 1 nm. All predictions are quantitatively compared to previously reported experimental data and a good agreement is obtained. An unusual red-shift observed for Ag particles in glass may be attributed to a thermal expansion mismatch induced lattice dilatation.

    Lattice defects in decahedral multiply twinned particles of palladium (1991)
    Springer
    The European physical journal 19 (1991), S. 307-310

    Notes: Abstract Multiply twinned decahedral particles of palladium have been studied by high-resolution electron microscopy in order to obtain evidence of lattice defects resulting from stress-relief processes due to internal elastic strains. This characterization revealed the presence of stacking faults parallel and adjacent to twin boundaries as well as inclined to twin boundaries. Additionally, for the first time stacking fault tetrahedra have been observed in the bulk of tetrahedral subunits. At the surface of the particles a pronounced micro-facetting has been shown to occur.
