“…The λ LSPR could be tuned by varying the thickness of the intermediate shell of Au. For synthesizing TAuT, the authors first modified the surface of the TiO 2 NP via layer-by-layer coating of polyelectrolytes [84][85][86][87]. Aqueous solution of modified TiO 2 NPs was then mixed with HAuCl 4 solution.…”

Abstract:The unique optical properties possessed by plasmonic noble metal nanostructures in consequence of localized surface plasmon resonance (LSPR) are useful in diverse applications like photovoltaics, sensing, nonlinear optics, hydrogen generation, and photocatalytic pollutant degradation. The incorporation of plasmonic metal nanostructures into solar cells provides enhancement in light absorption and scattering cross-section (via LSPR), tunability of light absorption profile especially in the visible region of the solar spectrum, and more efficient charge carrier separation, hence maximizing the photovoltaic efficiency. This review discusses about the recent development of different plasmonic metal nanostructures, mainly based on Au or Ag, and their applications in promising third-generation solar cells such as dye-sensitized solar cells, quantum dot-based solar cells, and perovskite solar cells.

“…Additionally, films of interlinked AuNP can be used to study the conductance of molecules [5,14,15]. For all of these applications the controlled synthesis of nanoparticle (NP) assemblies is a prerequisite [16]. In solution the most direct approach is inducing the formation of dendritic or dense spherical NP aggregates.…”

Abstract:We studied the aggregation of AuNP induced by small aromatic molecules under different conditions. In water, the aggregation was found to be difficult to control. Phase transfer of the particles into toluene by using oleylamine as a ligand allows for a more controlled and reliable synthesis. Using nonane-1,9-dithiol as a control, our experiments demonstrate that the molecular structure of the linker has a decisive influence on the aggregation. Aromatic dithiols yielded spherical aggregates in the range of 100 nm, whereas the aliphatic linker produced large aggregates in the µm range. The length of the aromatic linker (2 vs. 3 phenylene units) strongly affected aggregation kinetics and the structure of the produced aggregates. With UV/Vis and DLS based experiments it was possible to distinguish the process of ligand layer formation and aggregation. Our results will help to develop syntheses of defined spherical aggregates and possibly more complex structures.

“…[24][25][26] As observed in Figure 1b, an SPR band can be identified around 526 nm, however, with low intensity in the UV-Vis spectrum of the AuNP substrate. In the same UV-Vis spectrum a broad band around 700 nm is also observed, and it can be associated with the formation of AuNP junctions and aggregates, 27,28 as shown in the SEM images ( Figure 2) with different magnifications. The AuNP are uniformly distributed over all the entire surface of the glass support.…”

This study reports a functional passive sampler for monitoring gaseous elemental mercury (GEM). The material consists of gold nanoparticles (AuNP) deposited forming a film on thiolmodified glass slides. AuNP colloid was synthesized using sodium citrate, resulting in a size of 24.2 ± 0.8 nm, as determined by transmission electron microscopy analysis. For the indoor test, AuNP films were placed into Petri plates. One part of the lot was kept exposed to the laboratory's atmosphere and the other part was stored in closed plate (control). The films were removed from both plates along a month and analyzed using a direct mercury analyzer. A linear relationship between Hg retention and exposure time was obtained until the 23 rd day, which allowed to calculate a GEM retention rate of 2.2 ng g -1 day -1; the maximum retention capacity was around 50 ng g -1. This study provides an efficient method for indoor monitoring of GEM using AuNP films as passive sampler.
