Abstract: (1428 Views)
A silver metallic nanotube has a localized surface plasmon resonance in visible region. By solving Laplace’s equation in cylindrical coordinates, the local electric field in all regions of nanotube is taken which can be used to calculate enhanced electric field in any region. The enhancement of local electric field is one of the important factors in determining the SERS factor. Theoretical results show that the SERS factor near the inner wall of silver tube is about 4.36×1012 whereas near the outer wall of nanotube is about 2.57×1010. So, the silver nanotube system can be used as SERS substrate.
