Silver endotaxy in silicon under various ambient conditions and their use as surface enhanced Raman spectroscopy substrates

Morphology Effect on SERS Activity of Embedded Silver Nanostructures

“…In CVD technique, control over the growth of the nanostructures can be obtained by controlling the parameters like growth temperature, deposition time, and substrate orientation along with their initial conditions. In our previous articles, we have shown the use of the Ag endotaxial nanostructures grown by PVD method, annealed in different ambiences to vary the dimensions of the nanostructures and dielectric media around the nanostructures has been reported . In the present article, systematic study of shape, size, and coverage of these embedded Ag nanostructures on SERS enhancement factors with the help of standard analytes like crystal violet (CV) and Rhodamine 6 G (R6G).…”

SERS on Bimetallic Nanostructured thin films

“…To overcome several limitations of Raman spectroscopy such as low cross section and scattering, and weak intensity over sensitive detection, Surface-enhanced Raman Scattering (SERS) technique came into being a most appropriate and broadly used spectroscopy technique for the analysis and identi cation of chemical and biological species (Juluri et al 2015) in terms of both qualitative and quantitative analysis (Ignat et al 2014;Yi et al 2012).Being surface sensitive, this mechanism is e cient in detecting the molecules at much lower concentration even at single -molecular levels (Wong-ek et al 2010; Hu et al 2016; Kneipp et al1997;Michaels et al 1999;Xu et al 1999). SERS is highly preferable and superior over the existing conventional detection techniques such as HPLC, GC-MS, ELISA.…”
