“…In order to fit the experimental results obtained for the small nanoclusters, the permittivity of the PS-PAA polymer encapsulating the silver nanoclusters was modified to include a small imaginary part. Silver ions and impurities are known to diffuse into polymer, which in this case is enhanced by the higher temperatures during the encapsulation process, thus creating an effective absorbing medium 6 . Since the extinction coefficient κ depends on the ion and impurity concentration, it varies slightly from one sample to another.…”

All solutions were prepared using deionized water (resistivity > 18.2 MΩ•cm -1 ). Hydrogen tetrachloroaurate(III) hydrate, 99.9% (metal basis Au 49%) was purchased from Alfa Aesar; Amphiphilic diblock copolymer polystyrene-block-poly(acrylic acid)(PS 17 -b-PAA 83 , M n = 1800 for the polystyrene block and M n = 6000 for the poly(acrylic acid) block, M w /M n = 1.4) and thiol-terminated polystyrene (PS 115 -SH, M n = 12000; PS 18 -SH, M n = 2000) were purchased from Polymer Source, silver nanoparticles were purchased from nanoCompsix, spherical gold nanoparticles were purchased from nanopartz. Copper specimen grids (200 mesh) with formvar/carbon support film (referred to as TEM grids in the text) were purchased from XinXing BaiRui (T10023). CharacterizationTransmission electron microscopy (TEM) images were collected on a JEM-1400 (JEOL) operated at 100 ~ 120 kV. Scanning electron microscopy (SEM) images were collected at 300.000x magnification on a Quanta 650 FEG (FEI Company).

“…We have previously demonstrated [14] that silver nanoparticles formed at the glass surface during the first few µs of the laser exposure, are embedded into a liquid glass phase and then pushed into the outer regions where the viscosity is lower than in the center of the spot. Previous reports have mentioned that the irradiated spots are free of silver nanoparticles in either Ag + -doped glasses or in composite glasses containing silver nanoparticles after intense cw laser exposure at 244 nm or in the visible range [14,24,25]. It is thus likely that the silver nanoparticles involved in the periodic arrangement come from the depth of the exchanged layer, where the initial silver ions concentration is much lower than at the glass surface.…”

One-, two- or three-dimensional arrays of closely spaced silver nanoparticles may lead to new optical properties, due to short or long range coupling between their resonant surface plasmons, so that the spatially controlled growth of silver nanoparticles provides an efficient way to tune their optical properties. Towards this way, we present here the periodic pattern of a glass surface with silver nanoparticles by continuous ultraviolet laser exposure. The formation of the 160 nm period pattern is well described by an interference-based model which agrees with the experimental conclusions, mainly obtained by various forms of microscopy. Statistical approach based on the autocorrelation function gives quantitative description about the quality of the order in the periodic structure and about the nanoparticles averaged diameter (80 nm). We also present the optical extinction spectrum of the Laser Induced Periodic Surface Structure (LIPSS)-containing area of the glass, which unusually shows several bands in the visible range. The period of 160 nm of the periodic structure is short enough to allow coupling between nanoparticles, which makes it a possible candidate for plasmon-based optical applications.

“…For optimizing structural, optical and electrical properties of thin films, preparation techniques are usually combined by annealing process. [69][70][71][72][73][74][75][76][77] Annealing procedures can increase crystallinity and transmittance of thin films and reduce the defects of the crystalline structure. 65 78-80 In addition, studying of structural, morphological and optical properties of the prepared samples as a function of annealing temperature have been done and reported.…”

In this approach, Ag thin films have been prepared using electron beam evaporation technique onto a thin film of tin-doped indium oxide coated ordinary glass substrate. The fabricated thin films were annealed in various temperatures: 100, 200, 300 and 400 C and the effect of annealing on their wetting, structural and morphological properties has been investigated. Scanning electron microscopy (SEM), UV-Visible spectroscopy (UV-Vis), diffuse reflectance spectroscopy (DRS), X-ray diffraction (XRD) and contact angle measurement have been applied for the characterization and study of thin film surfaces. The results of SEM exhibit the aggregation and formation of Ag nanoparticles on the surface of substrate changed through increasing of annealing temperature. The presence of mixed In 2 O 3 -Ag phases in the as-prepared and annealed samples was confirmed by XRD pattern. Optical behavior of thin films was followed by using diffuse reflectance spectroscopy. Wettability studies showed that the contact angle of prepared thin films was influenced by various parameters such as annealing temperature, surface morphology and composition of thin films.
