英文摘要	NH2+ ion implantation was performed at the energy of 80 key with fluence of 2 x 10(16) ions cm(-2) for silicon, and the implantation of amino groups on the silicon surface was verified by X-ray photoelectron spectroscopy (XPS) analysis. Well-defined gold nanoparticles (AuNPs) film was formed with a sub-monolayer coverage on the obtained NH2+ ion implanted silicon (NH2/Si) surface, as revealed by the scanning electron microscopic (SEM) observations. Such AuNPs attached NH2/Si (AuNPs/NH2/Si) substrates showed a strong Surface-Enhanced Raman Scattering (SERS) effect, which enabled the detection of rhodanime 6G (R6G) at 10(-11) M. MH2+ ion implantation appears to be a viable approach of preparing reproducible SERS substrates for sensitive Raman detection. (C) 2012 Elsevier Ltd.
