采用一步法和两步法合成了新型发光杂化二氧化硅，并研究了它们的不同发光性能。结果表明，与一步法合成的样品相比，两步法合成的样品由于表面胺的高效性，其光致发光性能发生了明显的蓝移。采用XRD、TEM、FT-IR和N2吸附-脱附等手段对所得杂化材料的结构和织构进行表征，结果表明无机/有机纳米复合材料能够保持双峰介孔结构。最后提出了可能的介入机制。
Novel luminescent hybrid silicas have been synthesized through one-step and two-step methods and their different luminescent properties have been investigated. The results showed that the samples synthesized with two-step procedure exhibited a more evident blue shift of photoluminescence performance resulting from the high efficiency of surface amine than that by one-step route. The structure characteristic and texture properties of resultant hybrid silicas were characterized by XRD, TEM, FT-IR and N2adsorption–desorption techniques, indicating that inorganic/organic nanocomposites could maintain the bimodal mesoporous structure. Finally, a possible involved mechanism has been put forward.
