Abstract
Preparation and optical properties of silica gel glasses doped with Eu(III) chelates (the complexes of beta-diketones) are described. In particular th e emission and excitation spectra of the precursor salts and glasses are re ported. The assignment of electronic levels was proposed and the intensity analysis of the f-f transitions was performed. The decay times of D-5(0) le vels of Eu(III) complexes in gels are analyzed and compared with those repo rted for precursor salts. (C) 1999 Elsevier Science B.V. All rights reserve d.
