The organic part is a chromophore group derived from 2-benzoylbenzoic acid that is functionalized with trialkoxysilyl groups; the as-obtained silylated monomer is afterward submitted to complexation with Tb3+, and then it is used as the siloxane network precursor along with tetraethoxysilane. IR, NMR, UV-Vis absorption, low-temperature phosphorescence spectroscopy, and fluorescence spectroscopy were applied to characterization, and the above spectroscopic data reveal that the triplet energy of the organic ligand matches with the emissive energy level of Tb3+. The hybrid exhibits characteristic luminescence of Tb3+, and the change of hybrids's exciting wavelength also testifies to energy coupling and intramolecular energy transfer between the triplet state energy of organic ligand and the emissive level of Tb3+.
