摘要：

The preparation of highly crystalline and monodisperse Co and Fe nanoparticle is reported. Co and Fe nanoparticles were prepared by M2+-oleate(2) (M = Co and Fe) complex using thermal decomposition method. High-temperature (286 degrees C) reflux of octyl ether solution containing M2+-oleate(2) complex under Ar atmosphere generated monodisperse Co and Fe nanoparticles. Particle size of Co nanoparticles and Fe nanoparticles is 13.2 +/- 1.9 nm and 12.5 +/- 1.3 nm, respectively. Transmission electron microscopic (TEM) images of the particles showed two-dimensional assembly of particles, demonstrating the uniformity of these nanoparticles. The crystal structures of them were identified by using X-ray powder diffraction (XRD). The size and shape of nanoparticles were obtained by TEM images. Elemental analyses were conducted by using energy-dispersive X-ray microanalysis (EDX). The magnetic property was studied with vibrating sample magnetometer (VSM). (c) 2005 Elsevier B.V.
