| Outline of Final Research Achievements |
As a basis of the Raman analysis in the nano-interfacial area based on Electron Enhanced Raman Scattering (EERS) for in-situ analysis of the material removal mechanism by ultra-short pulse laser light, the measurement technique of localized and propagating surface plasmon enhanced Raman scattering (SERS) in chemical interaction between copper and fullerenol that is used as nano-particles for inducing EERS were investigated. The SERS analysis of copper-bypyridine-fullerenol reaction system was conducted to check the feasibility of time series measurements of both forward and back Raman scattering using the constructed measurement system. The propagating and localized SERS changing with the copper surface condition in the progress of chemical process could be detected simultaneously. The measuring results suggest the possibility to establish the in-situ surface analysis method in the nano-interfacial area based on the simultaneous measurement of the forward and back Raman scattering.
