本工作基于磁控溅射和等离子体处理工艺，展示了通过自组装方法制备的圆片级银纳米颗粒。制备了不同尺寸和形状的银纳米颗粒，系统研究了等离子体处理时间、等离子体气体组成和功率等因素对银纳米颗粒的影响，以发展一种低成本、大规模制备银纳米颗粒的方法。此外，还进行了表面增强拉曼散射实验：以结晶紫为探针，将其吸附在不同尺寸和密度的银纳米颗粒膜上，得到了表面增强拉曼散射和表面增强荧光现象。结果表明，该技术为银纳米材料的制备提供了一种快速的方法，适合于大规模生产，并与其他材料和生物传感器的制备相兼容。
In this work, the wafer-scale silver nanoparticles fabricated by a self-assembly method was demonstrated based on a magnetron sputtering and plasma treatment process. Silver nanoparticles of different sizes and shapes were prepared, and the effects of the plasma treatment time, plasma gas composition, and power were systematically investigated to develop a method for low-cost and large-scale fabrication of silver nanoparticles. Furthermore, the surface-enhanced Raman scattering experiments: crystal violet, as the probe, was absorbed on the silver nanoparticles film of different size and density, and get the phenomena of surface-enhanced Raman scattering and surface-enhanced fluorescence. The results show that the proposed technique provides a rapid method for the fabrication of silver nanomaterial; the method is adaptable to large-scale production and is compatible with the fabrication of other materials and biosensors.
