摘要：

Preparation and optical properties of silica gel glasses doped with Eu(III) chelates (the complexes of beta-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 D-5(0) levels of Eu(III) complexes in gels are analyzed and compared with those reported for precursor salts. (C) 1999 Elsevier Science B.V. All rights reserved.
