Abstract

Monodisperse MnFe2O4 nanoparticles with cubelike and polyhedron shapes were synthesized by reaction of Fe(acac)3 and Mn(acac)2 with 1,2-hexadecanediol, oleic acid, and oleylamine. Controlled evaporation of the particle dispersion led to nanoparticle superlattices. The crystal orientation of the particle in the assembly depends on the shape of the particles, with particles in a cubelike shape showing (100) texture and those in the polyhedron shape exhibiting (110) texture.

摘要

通过Fe(acac)3和Mn(acac)2与1,2 -十六烷二醇、油酸和油胺反应合成了具有立方状和多面体形状的单分散MnFe2O4纳米颗粒。颗粒分散体的可控蒸发导致纳米颗粒超晶格的形成。组装体中颗粒的晶体取向取决于颗粒的形状，立方状颗粒呈现(100)织构，多面体形状的颗粒呈现(110)织构。
