通过两种不同的负载方法(吸附和掺杂)成功地合成了含Eu3+的纳米多孔二氧化硅，并研究了Eu3+在结构中的存在状态。Eu~(3+)吸附表明Eu~(3+)与孔表面羟基和H2O分子相互作用增强猝灭，而Eu~(3+)掺杂则表明Eu~(3+)位于产生高效发光的结构骨架内。Eu3+与二氧化硅结构之间的相互作用取决于负载方法。
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.
