Studies of surface-enhanced Raman scattering of C60 Langmuir-Blodgett film on a new substrate.
Spectrochim Acta A Mol Biomol Spectrosc. 2008 Jun; 70(1):104-8.SA

Abstract

A new substrate of "gold nano-particle/silver nano-rod/ITO surface" was obtained by electrodeposition. Surface-enhanced Raman scattering (SERS) spectrum of high quality of C60 and stearic acid (SA) mixed Langmuir-Blodgett (LB) film shifted onto the new substrate was reported for the first time according to our knowledge. The results show that the substrate of "gold nano-particle/silver nano-rod/ITO surface" is very effective and active for C60 LB film. Furthermore, the C60 molecules are oriented on pentagons of C60 on the substrate. It is difficult to separate the electromagnetic and chemical mechanisms to the great enhancement of the Raman signal. On the one hand, the gold nano-particles grown on silver nano-rod surface perform an important action for magnifying the surface local electric field through the resonant excitation of surface plasma. And the needle-like rod may further magnify the local electric field because of lightning rod effect. On the other hand, charge transfer factor may not be neglected.
