Luminescent hybrid oxydiacetic/ethyleneglycol/TEOS/Eu(III) material: Thermal and spectroscopic analysis
A luminescent hybrid organic-inorganic 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 syste...
