A naturally grown Ag nanoparticle ensemble with a SPR wavelength at 491 nm was prepared by Volmer–Weber growth under ultrahigh vacuum condition. The surface enhanced Raman scattering (SERS) signal response and the SERS characteristics for fluoranthene in water were investigated with SERS/shifted excitation Raman difference spectroscopy using a Raman setup containing a microsystem light source at 488 nm. Research results reveal that SERS signal response time and detection limit are 9 min and 2 nmol/l, respectively.
