Enormous Surface-Enhanced Raman Scattering from Dimers of Flower-Like Silver Mesoparticles

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...

Summary: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.
