Novel organosilicates with covalently linked functional modified aromatic acid have been synthesized from 3‐aminopropyl triethoxysilane (APS) grafted 4‐ethoxy benzoic acid (EB‐Si) and terbium ions via a simple low‐temperature route. The existence of covalent bonds between EB‐Si and silica matrices was shown by the hydrolysis and polycondensation processes of ethoxysilyl groups. Luminescence spectra were used to characterize the photophysical properties of the obtained hybrid material and the above spectroscopic data reveal that the triplet energy of modified para ethoxy benzoic acid in this favorable hybrid system matches the emissive energy level of RE 3+ .
