摘    要:在三种带有不同电荷的表面活性剂构建的反胶束体系中(AOT/异辛烷、Oπ-10,环已烷、CTAB/正已醇)合成了BaMoO4的纳米粒子,采用透射电镜(TEM)观察其粒子呈球形,粒径在17-46 nm范围内,分布均匀;使用染料罗丹明B作为探针,采用紫外-可见光谱(UV-vis)和荧光光谱研究反胶束水池中罗丹明B与BaMoO4纳米粒子的相互作用;由于反胶束水池的空间和极性的限定,染料的光谱特征与其在纯水中发生很大变化,不同的反胶束体系中,由于染料分子所处的微观环境不同,导致其光谱特征也有较大区别。

关 键 词:反胶束  BaMoO4纳米粒子  罗丹明B  微环境  相互作用

Abstract:BaMoO4 nanoparticles were prepared in different reverse micelles and characterized with trans- mission electron microscopy (TEM). The absorption and fluorescence properties of RB have been investi- gated. The effects of surfactants on the interaction of rhodamine B (RB) with BaMoO4 nanoparticles in re- verse micelles have been also studied. The results showed that a small part of RB was adsorbed on the sur- face of BaMoO4. The formation of dimers of RB has also been discussed.
Keywords:reversed micelle  BaMoO_4 nanoparticle  rhodamine B (RB)  microenvironment  interaction
