Presentation Transcript

  1. Resonant SERS and electronic excitation • Ordinary infrared Raman involves only excitations in the electronic ground state • In order to get to the excited state one needs more energy

  2. Resonant SERS • To go to the electronic excited states one will have to utilize resonant SERS, SERRS • Else one will have to go to ultraviolet lasers

  3. Altered SERS • An interesting possibility is to consider: • Charge transfer from the nano particles • Changing the structure of the nano particles • Apply fields to the nano particles • Polarization and fusion effects with microwaves

  4. SERS-CT • Charge transfer enhancement mechanism of SERS (SERS-CT) is still controversial • The CT-mechanism is complicated • The mechanism consists of a charge transferred from excited states to radical anions

  5. Steps for charge transfer mechanism on SERS
