Enhanced Raman Scattering

A sol-gel technique has been used to synthesize silver decorated silica nanospheres for surface enhanced Raman scattering (SERS) substrates. X- Ray diffraction (XRD) spectra shows peak at 2θ = 38.1, 44.6, 64.7, and 77.5°confirming the presence of Ag nanoparticles on the substrates. The Ag- decorated silica nanospheres were applied as SERS substrates using Rhodamine 6G (R6G) as probe molecule. From Raman analysis, the highest SERS enhancement factor at R6G concentration of 102was calculated around ~1010.
