By means of Ostwald ripening self-assembly process
Ag nanoparticles substrates of various densities and sizes were fabricated.In the investigation of surface enhanced Raman scattering (SERS)and surface enhancement fluorescence (SEF)using crystal violet (CV)as a probe molecule
it was found that Raman and luminescence intensity varied in parallel with the Ag nanoparticles size.With increasing time of self-assembly process
the changes of intensity trended to be stabilized.The results indicated that SERS and SEF could be optimized by Ostwald ripening self-assembly.The results obtained could provide reference when developing long-term stability and cost-effective bio-chemical sensors based on SERS and SEF.
