N2 - This study demonstrates the size effect of silver nanocubes with the namely dimension 50 and 70 nm atop the massed silver surface (denoted, 50-NcIM and 70-NcIM) on surface enhanced Raman scattering (SERS) by using rhodamine 6 G and melamine with the irradiation of 532, 633, and 780 nm lasers. In addition, the NcIM substrate was exhibited a strong SERS effect under 633 and 780 nm laser irradiation. The enhancement factors of 50-NcIM and 70-NcIM samples were reached nearly 109 and 108, respectively. The simulation results show that plasmonic cavities (PC) derived from 50-NcIM and 70-NcIM respectively possess the stronger electromagnetic field density and the larger extended PC area under 633 and 780 nm laser irradiation, interpreting the experimental results well.
