Large-area Au-aggregate-assembled fractal patterns with tailored sizes and densities are achieved by sputtering Au nanoparticles on hexagonally patterned bowl-shaped-dimples on Al foil and subsequent annealing. After decorating with much smaller Ag nanoparticles, the resultant substrates exhibit an active and reproducible SERS effect.
大面积的 Au 聚集体组装分形图案，其尺寸和密度可以通过在 Al 箔上的具有六边形图案的碗状凹坑上溅射 Au 纳米颗粒，然后进行退火来实现。在经过更小的 Ag 纳米颗粒修饰后，得到的基底表现出了活跃且可重现的 SERS 效应。
