| Outline of Final Research Achievements |
We have aimed to create two-dimensional silver by using bilayer graphene and to have its applications of surface enhanced Raman spectroscopy.
As a notable result, we have succeed to fabricate a chemically stable surface-enhanced Raman scattering (SERS) substrate by using graphene. The substrate consists of graphene/Ag/SiO2/Si (G-SERS), and its graphene layer works as a protective layer for silver. We revealed that the G-SERS substrate has durability for concentrated hydrochloric acid and heated air (<400 degree C).
The present G-SERS substrates can be applied for molecular sensors and in-situ observation of chemical reactions in strong acid and high temperatures.
