Studying of Surface Enhanced Raman Scattering (SERS) spectrum of Ag nano thinfilm with Rhodamine6G and Graphen oxide.

Ag nano thinfilm with thickness 10 nm prepared on the clean coverslips glass, was done by using deposition vacuum system and the surface morphology done by atomic force microscopy (afm). nd-yag (532 nm) green laser and a 50x objective was used as a excitation source. composites of rh6g, go and silver nano thinfilm showed a good substrate for sers signals. strong sers signals indicating match the energy levels of materials interacting with each other and increase the free electrons in external shells, depending on the quantum mechanics.
