| 摘要: 在2-乙基己基琥珀酸酯磺酸钠(AOT)/异辛烷/水微乳液体系内，通过改变w值(水与AOT的物质的量之比)和反应物浓度比例得到了5 nm球形至80 nm立方状的NaKCoFe普鲁士蓝类配合物。发现w值和反应物浓度比不仅影响产物的形貌，而且影响配合物的结构。用UV、XRD、EDS、ICP、IR和超导量子干涉仪(SQUID)等对产品进行了结构和磁学性能的表征，发现影响产物磁性的主要因素是碱金属的含量。 |

| Abstract: Spherical and cubic nanoparticles of cobalt-iron Prussian blue analogues(NaKCoFe PBA) with morphologies from 5 nm sphere to 80 nm cube were synthesized in sodium bis (2-ethylhexyl) sulfosuccinate(AOT) /isooctane/water microemulsion, by tuning the water-to-surfactant molar ratio(w) and the concentration ratio of reactants. It is observed that reaction condition not only affects the morphologies of the products, but also has influence on the structure of the products. Furthermore, these products were characterized by UV, XRD, EDS, ICP, IR and superconducting quantum interference device magnetometer(SQUID) techniques. The results show that magnetic properties of NaKCoFe Prussian blue analogues are strongly influenced by the amount of the alkali cation. |
