Schematic representations of the optimization process and Raman spectra after the optimization. (a) Schematic representation of the optimization process. The left represents the contrast of the bitmap files before and after optimization; the right shows the optimized result after depositing gold film. (b) Raman spectra after the optimization. The thickness of gold film was 18nm; the sample probed was 10−6mol/L R6G.
