Resumo
Eu3+ fluorescence spectroscopy was used as a probe to study the changes in local arrangements of tin oxyhydroxide precipitate → sol → gel → glass conversion. Electronic transition intensities and 5D0 excited state lifetime variations were followed during the entire process. Adsorption of Eu3+ ions on the colloid and changes of chemical interactions occurring in each step are described. © 1992 Elsevier Science Publishers B.V. All rights reserved.
