| 摘 要： | 采用磁控溅射方法制备Ni纳米颗粒,使用扫描电镜(SEM)、原子力显微镜(AFM)等表征其形貌结构。采用高压溅射喷嘴结构,研究改变溅射压力等工艺参数对Ni纳米颗粒尺寸与形貌的影响。实验表明,采用高压喷嘴结构,溅射压力为20~180 Pa之间可以获得尺寸为10~100 nm的Ni纳米颗粒。采用高压溅射喷嘴结构可以得到具有晶体结构特征的Ni纳米颗粒。

| Abstract: | Ni nanoparticles were prepared by DC magnetron sputtering technique.The structural properties were characterized by means of scanning electron microscopy(SEM) and atomic force microscopy(AFM) respectively.The effect of sputtering pressure on the size and morphology of the sputtered Ni nanoparticles was studied using a sputtering configuration with high-pressure ejection nozzle.The results show that Ni nanoparticles with size from 10 nanometers to 100 nanometers can be obtained by DC magnetic sputtering with Ar pressure from 20 Pa to 180 Pa.The sputtering configuration with high-pressure ejection nozzle contributes to prepare the Ni nanoparticles with crystal structure characteristics. |
