Abstract: The strongest plasmonic band in UV-VIS absorption spectra is commonly supposed to be a sole characteristic of the optical properties of silver hydrosols determining their effectiveness in surface enhanced Raman spectroscopy (SERS). However, we found that the real enhancement coefficients of SERS correlate well with the contribution of the smallest nanoparticles rather than with overall light absorption as a feature of the whole ensemble of the nanoparticles of all fractions.
