- Two Eu complexes containing symmetrical and asymmetrical diphenanthryl β-diketone ligands have been incorporated into silicone rubber. Their luminescence properties have been investigated by luminescence spectra and lifetime measurements. According to the fluorescence emission spectrum, the Judd–Ofelt parameters Ω₂, Ω₄ of europium complexes doped silicone rubber have been calculated and the influence of ligand’s symmetry on the luminescence properties of Eu complex doped silicone rubber was discussed.
