Abstract

Preparation and optical properties of silica gel glasses doped with Eu(III) chelates (the complexes of β-diketones) are described. In particular the emission and excitation spectra of the precursor salts and glasses are reported. The assignment of electronic levels was proposed and the intensity analysis of the f-f transitions was performed. The decay times of 5D0 levels of Eu(III) complexes in gels are analyzed and compared with those reported for precursor salts.
