| 제목 | MXene blanked Au Nanoparticle monolayer for Ultra-sensitive Surface Enhanced Raman Scattering (SERS) Substrate |
| 초록 | The mechanisms for increasing the raman signal using the sers substrate are electromgnetic mechanism (EM) and charge transfer (CT), and it is difficult to use both. Recently, lots of studies for fabrications of Surface-enhanced Raman scattering (SERS) substrates in which novel metal and 2D nano sheet are combined have been researched to use EM and CT at the same time for large enhancement factor of SERS substrate However, to apply EM and CT at the same time, fermi level and hot spot must be considered. Therefore, we simultaneously proposed a monolayer of Au nanoparticles (AuNPs)/wiggled MXene bi layer for EM and CT work to enhance the Raman signal of Rhodamine B bound to the MXene surface to support hexavalent chromium (VI). To measure the E.F. of SERS substrate, the Rhodamine B solution was used as analytes. Since A lot of molecules can be bound to MXene due to the functional groups located outside the SERS substrate, It is expected to be utilized in a wide range of detection fields. |
