The active substrates in surface enhanced Raman scattering (SERS) spectroscopy were prepared through self-assembly of nanoparticles on functionalized glasses. Colloidal silver nanoparticles (Ag NPs) were prepared chemically in two different sizes by reduction of AgNO3 using trisodium citrate and sodium borohydride. Gold–silver core–shell nanoparticles were also prepared to compare between the o...
Nanostructure arrays such as nanowire, nanopillar, and nanocone arrays have been proposed to be promising antireflection structures for photovoltaic applications due to their great light trapping ability. In this paper, the optical properties of Si nanopillar and nanocone arrays in visible and infrared region were studied by both theoretical calculations and experiments. The results show that t...
Comparison between the results of strain and temperature dependent center Bragg wavelength shift have been accomplished using different apodization profiles to produce linearly chirped apodized far off resonance fiber Bragg gratings for the design of an optimum Dispersion compensator. The chirping is made using the ultraviolet (UV) phase mask method.
