Fourier transform absorption spectroscopy in the 500-6000 cm-1 and 9-300 K ranges is applied to monitor the effects produced by Eu3+ incorporation into sol-gel silica samples doped with concentration increasing from 0,001 to 10mol%. Evidences of clustering are found for high Eu3+ concentrations. For concentrations up to 3mol% the aggregates are amorphous as the silica matrix, while for the Eu3+ 10mol% sample they show a rather ordered structure.
