摘要

研究了,60,Co γ辐照硫酸铜水溶液体系制备纳米铜粉。用X射线衍射仪（XRD）、透射电子显微镜（TEM）、激光粒度仪分析（LSPSDA）和差示扫描量热仪（DSC）分别表征材料的结构、形貌、大小以及材料的熔点。结果表明，随着辐照剂量的逐步增加，辐照产物越接近纯铜，铜粒径逐渐减小，当辐照剂量达到400 kGy时辐照产物为纯铜。不同辐照剂量对粒子的形貌没有影响，粒子主要呈球形。

Abstract

60,Co γ-rays irradiation method was applied to prepare nano-particle copper in aqueous solution. The nano-particles with different sizes were prepared by use of irradiation with different absorbed doses. The samples were analyzed with X-rays powder diffraction (XRD), electron microscopy (TEM) and laser scattering particle size distribution analysis (LSPSDA), which were used to determine the constitution, shape and size distribution of the particle, respectively. It has been found that average size of copper nano-particle decreases with the increment of radiation absorbed dose. The sample is a mixture of cuprous oxide and pure copper when absorbed dose is low. And pure copper nano-particles can be obtained at 400 kGy. The morphology of the nano-copper particle can not be affected by absorbed dose and most particles are spherical.
