Fig. 7

a Physical model of 4MBA molecule movement in an exponentially decaying electromagnetic field with increasing of the distance Z perpendicular to the surface of substrate. The inset is the reorientation schematic of 4MBA molecule on the surface of the Ag/Ag-doped TiO2 substrate under laser irradiation. b Irradiation time-dependent SERS peak intensities of 4MBA at 364, 1078, and 1587 cm−1, experimental data (symbols) and theoretical results (solid lines).
