In contrast, a bulk Ag sheet, studied in cross section, showed an adherent corrosion layer of only around 20-50 nm in thickness after over a decade of being exposed to ambient air. The results have implications for antibacterial properties and ecotoxicology of AgNP during corrosion as the dissolution and reformation of Ag particles during corrosion will likely be accompanied by the release of Ag+ ions.]]> Wed 11 Apr 2018 12:52:26 AEST ]]> https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:11879 Wed 11 Apr 2018 12:33:20 AEST ]]> https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:4354 Wed 11 Apr 2018 11:59:45 AEST ]]> https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:11880 Wed 11 Apr 2018 09:59:10 AEST ]]> https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:7983 Wed 11 Apr 2018 09:44:54 AEST ]]> https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:32917 x WO₃) are vividly coloured metallic materials where the optical behaviour can be attributed to the bulk plasma frequency occurring in the visible part of the spectrum. A combination of density functional theory (DFT) calculations and experimental electron energy-loss spectroscopy (EELS) was used to assess their bulk and surface plasmon responses. It was observed that Na_x WO₃ can sustain strong localised surface plasmon resonances (LSPR) with an energy that can be tuned by changing the Na content. They have a stronger plasmonic response when compared to Au and do not suffer from the atmospheric corrosion of Ag, giving them good potential for plasmonic applications]]> Wed 02 Jun 2021 20:44:08 AEST ]]> https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:7986 Sat 24 Mar 2018 10:45:22 AEDT ]]> https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:5937 Sat 24 Mar 2018 10:24:20 AEDT ]]> https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:7075 Sat 24 Mar 2018 08:38:00 AEDT ]]> https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:19137 Sat 24 Mar 2018 07:55:54 AEDT ]]> https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:19315 Sat 24 Mar 2018 07:51:53 AEDT ]]> https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:18533 Sat 24 Mar 2018 07:50:12 AEDT ]]> https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:5408 Sat 24 Mar 2018 07:48:18 AEDT ]]> https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:28067 Sat 24 Mar 2018 07:39:47 AEDT ]]> https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:26812 Sat 24 Mar 2018 07:36:28 AEDT ]]> https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:29297 Sat 24 Mar 2018 07:34:12 AEDT ]]> https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:25899 Sat 24 Mar 2018 07:28:17 AEDT ]]> https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:4743 Sat 24 Mar 2018 07:21:06 AEDT ]]> https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:25150 Sat 24 Mar 2018 07:17:09 AEDT ]]> https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:24836 xAu_1-x (0 < x < 0.12) substitutional solid solutions is determined. Reflectance spectra and ellipsometric data of a range of compositions are measured and the dielectric functions extracted. Al additions flatten the reflection edge and increase optical loss in the Drude region. The implications of these changes for selected technological applications are investigated. Aluminium is found to be a very effective bleaching agent for Au and could have application for the formulation of improved 'white gold' jewellery alloys. However, due to its limited solubility in Au a-phase, other alloying additions would still be required to make a commercially acceptable 'white gold'. In contrast, the increased optical loss brought by the Al makes the alloys less suitable than pure Au for plasmonic applications or for spectrally selective coatings.]]> Sat 24 Mar 2018 07:15:11 AEDT ]]> https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:43928 xWO₃) is a promising alternative plasmonic material to nanoparticulate gold due to its strong plasmonic resonances in both the visible and near-infrared (NIR) regions. Additional benefits include its simple production either as a bulk or a nanoparticle material at a relatively low cost. In this work, plasmonic Na_xWO₃ nanoparticles were introduced and mixed into the nanoparticulate zinc oxide electron transport layer of a water processed poly(3-hexylthiophene):phenyl-C₆₁-butyric acid methyl ester (P3HT:PC₆₁BM) nanoparticle (NP) based organic photovoltaic device (NP-OPV). The power conversion efficiency of NP-OPV devices with Na_xWO₃NPs added was found to improve by around 35% compared to the control devices, attributed to improved light absorption, resulting in an enhanced short circuit current and fill factor.]]> Mon 29 Jan 2024 18:51:02 AEDT ]]>
