Abstract

Nanoparticles of lanthanum-strontium manganite were synthesized via different methods, namely, sol-gel method, precipitation from non-aqueous solution, and precipitation from reversal microemulsions. It was shown that the use of organic compounds and non-aqueous media allowed significantly decreasing of the crystallization temperature of nanoparticles, and the single-phased crystalline product was formed in one stage. Morphology and properties of nanoparticles depended on the method and conditions of the synthesis. The heating efficiency directly depended on the change in the magnetic parameters of nanoparticles, especially on the magnetization. Performed studies showed that each of these methods of synthesis can be used to obtain weakly agglomerated manganite nanoparticles; however, particles synthesized via sol-gel method are more promising for use as hyperthermia inducers.PACS: 61.46.Df 75.75.Cd 81.20.

摘要

通过不同方法合成了镧锶锰氧化物纳米颗粒，即溶胶 - 凝胶法、非水溶液沉淀法和反相微乳液沉淀法。结果表明，使用有机化合物和非水介质可显著降低纳米颗粒的结晶温度，且单相结晶产物可一步形成。纳米颗粒的形态和性质取决于合成方法和条件。加热效率直接取决于纳米颗粒磁性参数的变化，尤其是磁化强度。所进行的研究表明，这些合成方法中的每一种都可用于获得弱团聚的锰氧化物纳米颗粒；然而，通过溶胶 - 凝胶法合成的颗粒作为热疗诱导剂更具应用前景。
