The Regulation of Surface-Enhanced Raman Scattering Sensitivity of Silver Nanorods by Silicon Sections

الملخص EN

Vertically aligned silver nanorods were good substrates for surface-enhanced Raman scattering.

The surface-enhanced Raman scattering sensitivity of nanorods can be regulated through the method that the silver nanorod is divided into four uniform silver sections using five uniform silicon sections.

And the length of silicon sections is the key factor in regulating the surface-enhanced Raman scattering sensitivity.

In the regulation, the best surface-enhanced Raman scattering performance is about 4 times as large as the worst performance.

The study provides an effective way to regulate the surface-enhanced Raman scattering sensitivity of silver nanorods and its possible explanation about mechanism.
