Shape and size consistency of Ag nanoparticles is a challenging aspect when practical plasmonic devices are to be developed for their surface-specific activities. This study presents a simple chemical synthesis process which enables effective and rather uniform entrapment of Ag nanoparticles in dielectric oxide matrix at room temperature, without any assistance of physical/chemical agents. Uniformly...
Due to the industrial development, drinking water is getting polluted by disposing several waste products of the industries. Hardness is one of the prominent impurities in drinking water which is mainly due to the presence of carbonate and bicarbonate ions (CO32− and HCO3−) in it. Here, we present the synthesis of the zinc oxide (ZnO) and polyaniline (PANI) nanocomposite for...
We perform theoretical study of the nonlinear transmission and nonlinear diffraction in nanogratings etched at the surface of copper- and silver-based glass–metal composites. By assuming low metal concentration in the glass matrix, we employ Maxwell Garnett approach to obtain refractive index and absorption coefficient, while the optical nonlinearity of the composite is described using anharmonic...
