Abstract:
The surface-enhanced Raman scattering (SERS) of flower-like silver mesoparticle dimers with large hot areas is ≈10 to 100 times higher than the individual mesoparticles. The dependence of incident polarization illustrates that, even in the rough-surface mesoparticle dimer system, the coupling effect still dominates the SERS. More importantly, the micro-manipulator can be used to form dimers controlled with high SERS quality.
