Metallic nanorods synthesis and application in surface enhanced Raman spectroscopy
Metallic nanorods synthesized by oblique angle deposition on glass substrate are utilized as nano-scale structures that can be coated with SERS active metal to allow for excitation of surface plasmons. The synthesized nanorods have an average length of ~500-600 nm and are randomly distributed on the substrate. The SERS studies with Near-IR excitation at 785 nm show significant enhancement with ...
متن کاملUnification of Surface Enhanced Raman Spectroscopy of Dyes Using One Pot Synthesized Stabilized Ag Nanoparticles
stabilized Ag Nanoparticles (NPs) were synthesized using Lee-Meisel method under three different conditions in an oil bath. UV-Vis spectroscopy of the Ag NPs showed a Localized Surface Plasmon (LSP) band around 430 nm, indicating Ag NPs had a size range around 40 nm. To fabricate a surface Enhanced Raman Spectroscopy (SERS) substrate, LSP properties of Ag NPs was employed with the goal of detec...
متن کاملSurface Enhanced Raman Spectroscopy
Raman spectroscopy is the use of inelastic scattering of light to probe various properties of molecules and materials. Incoming photons interact with the electron cloud of the molecular bonds and inelastically scatter. During this scattering the energy of the incoming photon is shifted to red or blue depending on the particular process. This phenomenon is called Raman scattering and was discove...
متن کاملSurface-enhanced Raman spectroscopy.
The ability to control the size, shape, and material of a surface has reinvigorated the field of surface-enhanced Raman spectroscopy (SERS). Because excitation of the localized surface plasmon resonance of a nanostructured surface or nanoparticle lies at the heart of SERS, the ability to reliably control the surface characteristics has taken SERS from an interesting surface phenomenon to a rapi...
متن کاملAg Nanorods-Oxide Hybrid Array Substrates: Synthesis, Characterization, and Applications in Surface-Enhanced Raman Scattering
Over the last few decades, benefitting from the sufficient sensitivity, high specificity, nondestructive, and rapid detection capability of the surface-enhanced Raman scattering (SERS) technique, numerous nanostructures have been elaborately designed and successfully synthesized as high-performance SERS substrates, which have been extensively exploited for the identification of chemical and bio...
