“…The strongest electric field intensity enhancement was generated with a 10 nm thick Ag film. Using the AFM-based scratching method, Wang et al [ 46 ] obtained nanodot array structures fabricated with Au films of different thickness. The Au were 13, 20, and 40 nm thick.…”

“…Previous studies have shown that under visible light or near infrared excitation light, the SERS performance of rough aluminum surface is poor, while, rough gold, silver or copper surface has a strong surface enhancement effect [18][19][20]. Therefore, a gold film was coated on the machined aluminum-based ordered micro/nanostructure to prepare Au-Al surface-enhanced Raman substrate in this study, and the Schematic diagram of Raman detection principle is shown in Figure 2.…”

“…Previous studies have shown that under visible light or near infrared excitation light, the SERS performance of rough aluminum surface is poor, while, rough gold, silver or copper surface has a strong surface enhancement effect [18][19][20]. Therefore different spacing values is the same, the horizontal axis position of each spectral peak is the same, and the relative height of each spectral peak is also similar.…”
