In the present work, dimethyl ester-functionalized silane (DMAPMMS) was synthesized via a facile amino-ene reaction. Then the coordinated assembly of the ester ligands and lanthanide ions (Eu3+, Tb3+, Dy3+) occurred. The ester ligands were immobilized onto the Si-O network backbone via sol–gel processes. The particle size can be controlled to ca 50 nm by adjusting the solvent ratio. The terbium and europium-containing materials show sharp green and red emissions, respectively, which indicate that efficient intramolecular energy transfer took place in these luminescent silicone hybrids.
