Dependent light scattering and absorption patterns of metallic nano-sized particles in interaction with other spherical and cone-like structures were investigated. The numerical solution of the light scattering problem was obtained using DDSCAT7.0 code. The surface integration of the Poynting vector is performed to estimate the spectral absorption by individual particles. Parametric studies were conducted to examine the effects of different parameters, including the geometry, size, shape and the position of the particles, the wavelength, polarization and the direction of the incident light. It was observed that the proximity of particles contribute most to the intricate scattering and absorption patterns. The formulation provided on dependent light absorption and scattering may be used for diagnosis purposes and to improve the AFM based nano-manufacturing.

Effect of particle properties and light polarization on the plasmonic resonances in metallic nanoparticles Guler, Urcan; Turan, Raşit (2010-08-02) The resonance behavior of localized surface plasmons in silver and gold nanoparticles was studied in the visible and near-infrared regions of the electromagnetic spectrum. Arrays of nano-sized gold (Au) and silver (Ag) particles with different properties were produced with electron-beam lithography technique over glass substrates. The effect of the particle size, shape variations, period, thickness, metal type, substrate type and sulfidation were studied via transmission and reflectance measurements. The re...
Nonlinear optical properties of low temperature annealed silicon-rich oxide and silicon-rich nitride materials for silicon photonics Minissale, S.; Yerci, Selçuk; Dal Negro, L. (2012-01-09) We investigate the nonlinear optical properties of Si-rich silicon oxide (SRO) and Si-rich silicon nitride (SRN) samples as a function of silicon content, annealing temperature, and excitation wavelength. Using the Z-scan technique, we measure the non-linear refractive index n(2) and the nonlinear absorption coefficient beta for a large number of samples fabricated by reactive co-sputtering. Moreover, we characterize the nonlinear optical parameters of SRN in the broad spectral region 1100-1500 nm and show ...
Effective mass and peculiarity of optical properties of Cadmium Sulfide nanoparticles Muradov, M. B.; Eyvazova, G. M.; Turan, Raşit; Maharramov, A. M. (2008-12-01) X-ray diffraction data, electron microscope and optical properties of cadmium sulfide nanoparticles were analyzed. It is shown that the value of the reduced effective mass of charge carriers in nanoparticles differs from bulk crystals. Changes of effective mass and "red shift" in values of band gap are explained by the occurrence of additional electronic potential in nanoparticles.
Dispersive optical constants of Tl2InGaSe4 single crystals Qasrawi, A. F.; Hasanlı, Nızamı (IOP Publishing, 2007-09-01) The structural and optical properties of Bridgman method grown Tl2InGaSe4 crystals have been investigated by means of room temperature x-ray diffraction, and transmittance and reflectance spectral analysis, respectively. The x-ray diffraction technique has shown that Tl2InGaSe4 is a single phase crystal of a monoclinic unit cell that exhibits the lattice parameters of a = 0.77244 nm, b = 0.64945 nm, c = 0.92205 nm and beta = 95.03 degrees . The optical data have revealed an indirect allowed transition band ...
