An optical probe of the structure of metal ion centers in sol-gel systems based on Eu3C and Nd3C
emission and absorption measurements has been developed. The effects of the structure and composition of organic
complexes of Eu3C on the clustering processes and retention of water molecules in the gel and glasses were
investigated. Mechanical properties of systems prepared with Triton detergent were also investigated. The studies
have been performed for two types of complexes of lanthanides, with ¯-diketones as the precursor lanthanide salts.
The emission, excitation and absorption spectra of the precursor salts, gels and glasses heated to 1100 K were
measured. Splitting of the levels and electronic transition probabilities were analyzed. The IR spectra were used
for the detection of the OH¡ modes in the glasses.
