Abstract

Ultra-small magnetic FeO nanoparticles are successfully synthesized in basic solutions by using the radiolytic method of the partial reduction in Fe in the presence of poly-acrylate (PA), or by using the coprecipitation method of Fe and Fe salts in the presence of PA. The optical, structural, and magnetic properties of the nanoparticles were examined using UV-Vis absorption spectroscopy, high-resolution transmission electron microscopy (HRTEM), X-ray diffraction (XRD), and SQUID magnetization measurements. The HRTEM and XRD analysis confirmed the formation of ultra-small magnetite nanoparticles in a spinel structure, with a smaller size for radiation-induced particles coated by PA (5.2 nm) than for coprecipitated PA-coated nanoparticles (11 nm). From magnetization measurements, it is shown that the nanoparticles are superparamagnetic at room temperature. The magnetization saturation value = 50.1 A m kg of radiation-induced nanoparticles at 60 kGy is higher than = 18.2 A m kg for coprecipitated nanoparticles. Both values are compared with nanoparticles coated with other stabilizers in the literature.

摘要

通过在聚丙烯酸酯（PA）存在下对铁进行部分还原的辐射分解法，或在PA存在下铁与铁盐的共沉淀法，在碱性溶液中成功合成了超小磁性FeO纳米颗粒。使用紫外可见吸收光谱、高分辨率透射电子显微镜（HRTEM）、X射线衍射（XRD）和超导量子干涉仪（SQUID）磁化测量对纳米颗粒的光学、结构和磁性进行了研究。HRTEM和XRD分析证实形成了具有尖晶石结构的超小磁铁矿纳米颗粒，PA包覆的辐射诱导颗粒（5.2 nm）的尺寸小于共沉淀的PA包覆纳米颗粒（11 nm）。通过磁化测量表明，纳米颗粒在室温下具有超顺磁性。60 kGy下辐射诱导纳米颗粒的磁化饱和值 = 50.1 A m kg高于共沉淀纳米颗粒的 = 18.2 A m kg。将这两个值与文献中涂覆有其他稳定剂的纳米颗粒进行了比较。
