The researches of surface enhanced Raman scattering spectrum enhancement factor are based on low concentration of the solution, while the selection of solution concentration on the enhancement factor is ignored. In this paper, the substrate of nano-pillar forest structure whose density is controllable was fabricated. Using the high ability of enhancement, Raman scattering enhancement under different concentration (10g / L ~ 10-5 g / L) was tested and researched .The results indicate that the enhancement factor has close relationship with concentration, that is to say the enhancement factor will arise with the concentration decreasing. The main element, which affects the variation of the enhancement factor, is due to the change of efficiency polarization of CV molecule adsorbed on the Au nano- pillar.
