The synthesis of 3-(triethoxysilyl)-propyl isocyanate (TEPIC) modified by (3-aminopropyl)triethoxysilane (APS) and the preparation of the corresponding organic-inorganic molecular-based hybrid material with the two components equipped with covalent bonds is described. The coupling agent moiety is a convolution of TEPIC and APS through -NHC( O)NH-groups, which is applied to coordinate to RE 3+ and further formed Si-O backbones after hydrolysis and polycondensation processes. For comparison and luminescence efficiency purposes, we added 2,2-bipyridyl to the above hybrids in order to increase the conjugating effects and sensitize rare earth ions emissions. Luminescence spectra were utilized to characterize the photophysical properties of the hybrid material obtained, and the above spectroscopic data reveal that the triplet energy of 2,2-dipyridyl in this favorable hybrid system matches with the emissive energy level of RE 3+ . In this way, the intramolecular energy transfer process took place within these molecular-based hybrids and strong green and red emissions of RE 3+ have been achieved.
