Paper Abstract

Eu3+ and U022+ have been used as optical probes iii sol-gel silica. Optical fluorescence and decay times were monitored as a function of processing parameters such as pH and densification temperature, and the optical data were correlated with structural changes in the materials. Fluorescence and decay times of Eu3+ ljO,2+ co-doped materials were studied and energy transfer effects were interpreted in terms of the pore morphology.
