Abstract

Europium (III) (Eu³⁺)-containing nanoporous silicas were successfully synthesized by two different loading methods (adsorption or doping), and the states of the Eu³⁺ in the structure were investigated. The Eu³⁺-adsorption indicated that the Eu³⁺ interacts with hydroxyl groups on the pore surface and H₂O molecules to enhance the quenching, whereas the Eu³⁺-doping indicated that the Eu³⁺ was located inside the structure framework that produced the efficient luminescence. The interaction between the Eu³⁺ and silica structure depended on the loading method.
