Abstract

The importance of the photothermal effect in surface enhanced Raman scattering (SERS) measurements is addressed. Strong temperature gradient (≈106 K m-1) induced by photothermal effect can force molecules to move. Finally, redistributed molecules can result in a nonuniform SERS intensity.
