| 摘 要： | 在水溶液中，常温常压下不加入任何催化剂，用电子束加速器辐照作为一种新的方法可成功制备纳米镍。利用X射线衍射(XRD)、透射电子显微镜(TEM)、激光衍射粒度分布仪(LSPSDA)、紫外可见光分光光度计(UV)、样品振荡磁力计(VSM)和差热分析仪(DSC)来分别表征材料的结构、形貌、大小、粒径分布、光学特征、磁学性能以及材料的熔点。TEM图像和LSPSDA分布图证明颗粒大小为39nm，这与XRD实验通过Scherer理论公式计算的结果相一致。

| Abstract: | A new method, using electron beam, has been successfully developed to prepare nickel nano-particles at room temperature under ambient pressure, without any catalyst. The structure, morphology, size, size distribution, optical properties, magnetic properties and the melting point have been characterized by X-ray diffraction (XRD), laser scattering particle size distribution analysis (LSPSDA), transmission electron microscopy (TEM), ultraviolet-visible spectrophotometer (UV-vis), vibrating sample magnetometer (VSM) and differential scanning calorimeter (DSC), respectively. The LSPSDA and TEM results show that average size of the nickel nano-particles is about 39 nm, which is in agreement with the calculated value from XRD using Scherer formula. |
