Title: Optical Characterization of Electro-spun Polymer Nanofiber based Silver Nanotubes,
Abstract: Nanotubes of various kinds have been prepared in the last decade, starting
from the discovery of carbon nanotubes. Recently other types of nanotubes
including metallic (Au), inorganic (TiO2, HfS2, V7O16, CdSe, MoS2), and
polymeric (polyaniline, polyacrylonitrile) have been produced. Herein we
present a novel synthetic procedure leading to a new kind of porous,
high-surface-area nanoparticle nanotubes (NPNTs). This study characterizes the
synthesized silver nanotubes at optical wavelengths. The absorption spectrum of
PAN washed silver nanotubes shows an extended absorption peak at visible
wavelengths ranging from 350 to 700 nm. In addition, the absorption spectrum of
randomly oriented silver nanotubes showed plasmonic behavior, indicating high
efficient surface enhanced Raman scattering (SERS) performance.
