Resumen:
Abstract: A luminescent hybrid organicinorganic material
was synthesized with the sol-gel technique by hydrolysis
of tetraethoxysilane (TEOS) and an organic precursor
obtained through the esterification of oda (oxydiacetic
acid) and EG (ethyleneglycol) in acid media. The Eu(III)
ion was included in the system to monitor the formation of
the complex between the lanthanide and the ligand oda in
the hybrid matrix. The spectral features of the emission of
the Eu(III) ion together with the data obtained from
infrared spectroscopy, thermogravimetric and differential
thermal analysis, and scanning electron microscopy permit
the structural characterization of the system and its comparison
with a reference sample in which no organic
moieties were hydrolyzed during the solgel process.
