　　Summary:
　　Layered hydroxides has a unique structural features and excellent optical, electrical, and magnetic properties, which in theoretical research and practical applications are of great significance. How to control the synthesis of different morphology, structure and composition of the layered compounds to study the morphology of nano-materials and for the relationship Magnetic lifter between physical properties, its further assembly as structure primitives, composite applications is essential. As the one-dimensional materials with unique electrical, optical and mechanical properties, therefore, this paper is committed to synthesis of rare earth hydroxide nanowires layered structure, and its performance and application of a preliminary study.
　　Design and development of a no template, in ethanol-water mixture prepared under solvothermal conditions acetate ion intercalation of layered porous lanthanum compounds, new methods of nanowires. Achieved by changing the experimental conditions on the nanowire diameter control; by Eu doping, giving the fluorescent properties of new materials; change intercalation ion, synthesis of different anions intercalated layered compounds of lanthanum nanowires. While the synthetic materials used in dilute solution in the short-stranded DNA capture and release of DNA fast, Congo red dye wastewater adsorption separation, showing good performance, for further biological, environmental and other fields foundation.
　　The ethanol-water mixtures by the thermal method of layered porous lanthanum compound nanowire system extended to the light rare earth systems, layered synthesized a series of light rare earth hydroxide nanowires; change the experimental http://www.999magnet.com/products/131-magnetic-lifter conditions, reaction temperature and reaction time for the layered structural changes, and found that low temperature and short-term help to maintain the structure of layered compounds. While a preliminary study of europium hydroxide nanorods and nanowires and layered hydroxide Eu fluorescence properties. The synthesis of layered rare-earth hydroxide nanowires and combine the advantages of a layered structure, it is possible to build functional nanostructures as a further structural primitives.
