Confined lead nano-granules investigated with X-ray absorption spectroscopy

In the present contribution we show that X-ray absorption spectroscopy may be an effective way to obtain a detailed insight into nano-granular structures embedded in a glass matrix. For the first time we have employed the single energy X-ray absorption detection method to determine the diameter distribution of metallic granules embedded in a glass matrix. In particular, we have estimated the diameter distribution of Pb granules confined in a PbOSiO(2) matrix.
