Preparation and Raman enhancement properties of gold nanostars
Gold nanostars(GNSs)have a series of sharp tips structures,which will produce strong hot spots and have great application potential in Raman enhancement.In this paper,muti-tip GNSs have been prepared experimentally,and the control techniques of their tip and size have been mastered.For the first time,a fast and efficient self-assembly technique without additives has been developed,and a series of Surface Enhanced Raman Scattering(SERS)substrates have been successfully prepared by using this technique.The effect of different GNSs density of substrates on SERS signal is further studied experimentally.The results show that the SERS signal is closely related to the density of particles in the substrate.The higher density of GNSs in the substrate,the more hot spots covered by the incident light plate,and the greater contribution to the SERS signal.
