Abstract

Eu³⁺-doped and suifosalicylic-acid (Sal)-doped SiO₂-B₂O₃ xerogels were prepared separately using the sol - gel method. The structure of SiO₂-B₂O₃ xerogels with different SiO₂/B₂O₃ ratio was studied by infrared (IR) spectra and fluorescence spectra with Eu³⁺ and sulfosalicylic acid as a probe. Furthermore, the structural evolution in SiO₂-B₂O₃ xerogels to glass conversion was also studied. The results showed that devitrification or crystallization did not take place in the experimental heat-treatment temperature range up to 800°C. At low temperature the B-O bonds were essentially non-bridge links, which at latter stages evolved towards terminal Si-O-B bonds. The three-dimensional Si-O-B network could be formed upon heating to 500°C. © 1998 Elsevier Science B.V. All rights reserved.
