Abstract
  • When an electromagnetic radiation interacts with a metal, the conduction electrons can be trapped in surface nanosize struc-tures giving rise to collective excitations called surface plasmons.These latter are responsible of the SERS (surface-enhanced Raman scattering)eff ect,which provides huge magnifi cation ofthe Raman signal of molecules adhering to nanostructured sur-faces of metals like silver,gold or copper.The surface plasmonresonances have also a sizeable eff ect on the fl uorescence of theligand/metal systems,increasing the excitation effi ciency neces-sary for the fl uorescence emission and producing surface-enhanced fluorescence (SEF).When an electromagnetic radiation interacts with a metal,theconduction electrons can be trapped in surface nanosize struc-tures giving rise to collective excitations called surface plasmons.These latter are responsible of the SERS (surface-enhancedRaman scattering)eff ect,which provides huge magnifi cation ofthe Raman signal of molecules adhering to nanostructured sur-faces of metals like silver,gold or copper.The surface plasmonresonances have also a sizeable eff ect on the fluorescence of theligand/metal systems,increasing the excitation effi ciency neces-sary for the fluorescence emission and producing surface-enhanced fl uorescence (SEF).
