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.

BaMoO4 nanoparticles were prepared in different reverse micelles and characterized with transmission electron microscopy (TEM). The absorption and fluorescence properties of RB have been investigated. The effects of surfactants on the interaction of rhodamine B (RB) with BaMoO4 nanoparticles in reverse micelles have been also studied. The results showed that a small part of RB was adsorbed on the surface of BaMoO4. The formation of dimers of RB has also been discussed.

Key words: reversed micelle, BaMoO4 nanoparticle, rhodamine B (RB), microenvironment, interaction
