摘要
采用 NaBH4 将 NiCl2∙6H2O 中的镍离子一步化学还原的方法，在室温下合成了镍纳米粒子。通过 X 射线衍射、拉曼光谱、扫描和透射电子显微镜研究了纳米粒子的微观结构。对 X 射线衍射和拉曼光谱数据的分析表明，获得的纳米粒子具有立方金属镍结构，晶粒大小（相干散射区）为 3-6 纳米。形态学研究表明，纳米镍粒子呈球形，相互接触形成大的纳米颗粒团聚体。
Microstructure and Optical Characteristics of Nickel Nanoparticles Obtained by One-Step Synthesis Method
Nickel nanoparticles were synthesized at room temperature by a one-step method of chemical reduction of Ni ions from NiCl2∙6H2O using NaBH4. The microstructure of the nanoparticles was studied by x-ray diffraction, Raman spectroscopy, and scanning and transmission electron microscopy. An analysis of x-ray diffraction and Raman spectroscopy data showed that the obtained nanoparticles had the cubic metallic Ni structure with a crystallite size (coherent scattering region) of 3–6 nm. Studies of the morphology indicated that the Ni nanoparticles were spherical in shape and in contact with each other to form large agglomerates of nanograins.
