    Notizen: 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.

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

    Notizen: 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.
