Solution-phase synthesis of single-crystalline magnetic nanowires with high aspect ratio and uniformity

摘要

Single-crystalline Fe3O4 nanowires with uniform diameters and the largest aspect ratio (> 500) were prepared by a one-step sol - gel process in the presence of ethylene glycol and poly( ethylene glycol)- block-poly( propylene glycol)- block-poly( ethylene glycol).
