Yiping ZhaoSubstrates consisting of silver nanorod arrays with an irregular surface lattice (i.e., random nucleation sites) and with varying rod lengths were fabricated by an oblique angle vapor deposition method. These arrays were evaluated as potential surface-enhanced Raman spectroscopy (SERS) substrates using trans-1,2-bis(4-pyridyl)ethene as a reported molecule. SERS activity was shown to depend upon the length of the nanorods. The Ag nanorods with average lengths of 508.29±44.86nm, and having aspect ratios of 5.69±1.49 exhibited the maximum SERS enhancement factors of greater than 108. Theoretical calculations indicate that this large SERS enhancement may be partially explained by the shape, density, and lateral arrangement of the Ag nanorod arrays.

Using a pump–probe method with a 150 fs laser at the wavelength of 1.55 μm, we have experimentally demonstrated that single-walled carbon nanotubes (SWNT) have an exciton decay time of less than 1 ps and a high third-order polarizability, which is reasonably interpreted as due to their azimuthal symmetry. These experimental results reveal that a SWNT polymer composite may be a candidate material for high-quality subpicosecond all-optical switches.
About Me
Dr. Yiping Zhao received his B.S. degree in electronics from Peking University in 1991, and his MS degree in condensed matter physics from the Institute of Semiconductors, Chinese Academy of Sciences, in 1994. He obtained his PhD in physics at the Rensselaer Polytechnic Institute in 1999. He is currently a distinguished research professor at the Department of Physics and Astronomy in the University of Georgia, a fellow of SPIE (the International Society of Optics and Photonics), and a fellow of AVS (American Vacuum Society). His major research interests are nanostructures and thin-film fabrication and characterization, plasmonic nanostructures, chemical and biological sensors, nano-photocatalysts, antimicrobial materials, nanomotors, and nanotechnology for stroke treatment.
