Abstract: AbstractWe investigated the formation of very small Ag nanoparticles of 1-2 nm size in soda-lime glass with enhanced amounts of iron oxide by Ag/Na ion exchange procedures. The duration of ion exchange has been chosen between 20 and 600 h to study the processes systematically. It could be shown that structural relaxations take place as the Ag + ions were incorporated into the glass replacing the Na + of the original matrix. X-ray absorption spectroscopy at the Fe K-edge demonstrated that polyvalent Fe ions se…
