Abstract

This work focuses on the construction of a series of novel chemically bonded inorganic–organic rare earth hybrid materials using 3,4-bis(pyridin-4-ylmethoxy)benzoic acid as an organic bridge molecule that can both coordinate with rare earth ions and form an inorganic network with titanium isopropylate and aluminum isopropylate after cohydrolysis and copolycondensation through a sol–gel process. Measurements of the properties of these materials show that the terbium systems present high thermal stability and amorphous structure features. UV excitation in the organic component resulted in strong green emission from Tb3+ ions due to an efficient ligand-to-metal energy-transfer mechanism.
