Optical investigation of Sm(III)-beta-diketonate complexes with different neutral ligands.

The optical properties of three Sm(III)-beta-diketonate complexes with different neutral ligands in methyl methacrylate have been investigated and the influence of the neutral ligand on fluorescence emission, Judd-Ofelt intensity parameters and metastable state lifetime was analyzed. The eta intensity parameters and Judd-Ofelt intensity parameters were obtained from fluorescence emission spectra and absorption spectra, respectively. The metastable state lifetime measurements correspond with the results obtained from fluorescence emission spectra and absorption spectra.
