FIG. 1.

Raman spectra at 442 nm of a-C(5 nm)/Si (a) before (i), and after thermal processing (ii). Curves fitting are added in solid lines. Typical Raman spectrum at 442 nm of Ni/a-C(20 nm)/Si after thermal annealing at 780 °C (b).

FIG. 2.

Typical SEM images of Ni/a-C(20 nm)/Si after thermal processing at 780 °C before (a) and after Au NPs decoration (b).

Image of FIG. 3.
FIG. 3.

Raman spectra of R6G(10−6 M), R6G(10−6 M)-Au/Si, fl-graphene, Au-fl-G, and R6G(10−6 M)-Au-fl-G at 633 nm and 488 nm wavelengths (a); typical Raman mapping at 633 nm of R6G (10−6 M) dropped on Au-fl-G (b); typical SERS spectra from the spots marked with corresponding colored cross in (b) are shown in (c).

Image of FIG. 4.
FIG. 4.

Raman spectra at 633 nm of ATP (a) and deltamethrin (b) deposited on Au-fl-G at different concentrations (from 10−6 M to 10−3 M). The arrows indicate the peaks position of ATP and deltamethrin.
