Determination of size and concentration of copper nanoparticles dispersed in glasses using spectroscopic ellipsometry

On the use of localized plasmon polaritons in solar cells

“…This can in principle be done by adding the desired substances in ionic form to the glass-forming compounds. Depending on the available reducing agents in the mixture, in some cases the metal intended for nanoparticle formation can be reduced and particle precipitation is observed during fusion of the glass [57]. Often, however, the majority of metal atoms, in this case, leave the glass melt before precipitation, and a very special processing, very different from commercial glass production, would be necessary.…”

Structure of Intercalated Cs in Zeolite ITQ-4: An Array of Metal Ions and Correlated Electrons Confined in a Pseudo-1D Nanoporous Host

“…Nanoscale arrays of metal atoms are being extensively studied because they often exhibit interesting and useful properties not occurring in bulk metals. Examples include nanomagnets [1], nanocatalysts [2], composites with improved optical properties [3] and nanodevices [4]. The subject of this letter is the class of novel, and poorly understood, low-dimensional electron systems known as "electrides" [5,6].…”

“…However, materials constructed at the nanoscale often do not possess the translational symmetry and long-range order of conventional crystals. Instead they assume structures of reduced dimensionality and/or accommodate a large number of defects and local disorder [1][2][3][4][5][6]. The diffraction patterns of such materials show a pronounced diffuse component and few Bragg peaks, if any.…”

A tri-block copolymer templated synthesis of gold nanostructures

“…As shown in Fig. 7, the histograms from B and C samples present well-defined Gaussian profiles [40][41][42][43], with average radius, r avg, , of 2.0 nm and 3.4 nm and polydispersity, 2 p, of 0.22 and 0.15, respectively. It is worth to note that, increasing the polymer concentration gold nanoparticles grow in a symmetric way; TEM images on sample C reveal the formation of ''dimers'' and ''trimers'' as well as the superposition of ''monomers'' as induced by the presence of an excess of BMB in respect of gold precursor.…”
