“…Several studies reported the relation between NP shape and LSPR wavelength shift. Spheroidal NP models were mainly used in these studies 24,26,27 and it has been shown that these results are not applicable to non-spheroidal NPs. Although several studies 28,29 have focused on particle shapes other than spheroids, they generally have used a single statistical model in which only one average shape is considered, rather than the actual size and shape distribution.…”

Metal nanoparticles (NPs) exhibit localized surface plasmon resonance (LSPR) and thus have potential for use in a wide range of applications. A facile technique for the preparation of NP films using an electron-cyclotron-resonance plasma sputtering method without a dewetting process is described. Field emission scanning electron microscopy (FE-SEM) observations revealed that the Au NPs grew independently as island-like particles during the first stage of sputtering and then coalesced with one another as sputtering time increased to ultimately form a continuous film. A plasmon absorption peak was observed via optical measurement of absorption efficiency. The LSPR peak shifted toward longer wavelengths (red shift) with an increase in sputtering time. The cause of this plasmon peak shift was theoretically investigated using the finite-difference timedomain calculation method. A realistic statistical distribution of the particle shapes based on FE-SEM observations was applied for the analysis, which has not been previously reported. It was determined that the change in the shape of the NPs from spheroidal to oval or slender due to coalescence with neighbouring NPs caused the LSPR peak shift. These results may enable the design of LSPR devices by controlling the characteristics of the nanoparticles, such as their size, shape, number density, and coverage. V C 2014 AIP Publishing LLC.

“…Arrays of nanodots with the use of anodic alumina templates are formed with the use of diversity techniques (Table 4), including pulse laser deposition (Ag, Ni, Zn [179]), vacuum sputtering (Ag, Au [162]), electron beam evaporation (Ag [28,155], Au [118][119][120]), electron beam epitaxy (Fe [149]), AC electrodeposition (Au [117]), and pulse electrodeposition (Cu-Ni [79]). Electronic, optical, and magnetic properties of the obtained nanodots were investigated in details.…”

Anodic aluminum oxide (AAO) consists of parallel pores arranged in a honeycomb-like array. Since a two-step self-organized approach in anodic alumina fabrication was invented, tremendous attention was paid to this material. Structural features of anodic alumina, like pore diameter, interpore distance, and nanoporous oxide thickness, can be fully controlled by operating conditions, including type, concentration and temperature of the electrolyte, applied voltage, and duration of the anodization process. Moreover, these operating conditions have also a major impact on the nanoporous array arrangement. Quantitative arrangement analysis methods employing fast Fourier transforms have been developed to assess the nanopores' arrangement. The most frequent application of the anodic aluminum oxide is a template-assisted fabrication of nanostructures. Templates made of the AAO are being successfully applied in fabrication of nanowires, nanotubes, and nanodots by using diversity of techniques, including electrochemical deposition, physical and chemical vapor deposition, sol-gel techniques, etc. Due to the size of obtained nanostructures, magnetic, electric, piezoelectric, luminescent, and catalytic properties of the deposited materials can be significantly improved. Thus, control of the nanopores' structural features and arrangement is crucial for AAO applications in nanotechnology.

“…This technique facilitates the control of the geometric pattern of nanoparticles, but it has some drawbacks such as high cost and large-area patterning. Owing to these limitations, 2D metal nanoparticle arrays have been fabricated by nonlithographic techniques using self-organized nanostructured materials as a template [4,[8][9][10][11][19][20][21][22][23][24][25][26][27]. Among the materials, a self-organized anodic aluminum oxide (AAO) layer with uniform through holes of nanometer dimensions has been widely used as a shadow mask to fabricate 2D NDAs of various materials [20][21][22][23][24][25][26][27].…”

“…However, the plasmonic properties of metal NDAs produced using AAO masks have not been reported widely. Several studies have reported the LSPR of Ag or Au NDAs with height variations by varying the amount of metal deposited using AAO masks with similar pore diameters [24][25][26]. However, the LSPR of metal NDAs with different diameters of similar height has not yet reported due to the difficulty of controlling the pore diameter of the AAO mask.…”

“…The most challenges in preparing the AAO mask are to completely remove the barrier layer at the bottom and control the pore diameter. In order to obtain an ultrathin AAO mask, the removal of the barrier layer and pore widening were performed by chemical etching in 5% H 3 PO 4 or by Ar + milling [24][25][26][27][28][29][30]. The Ar + ion milling method for the barrier layer removal is expensive and time-intensive [28].…”

Anodic aluminum oxide (AAO) layers with nano-sized pores have been used as shadow masks for the fabrication of two-dimensional (2D) metal nanodot arrays (NDAs). However, the localized surface plasmon resonance (LSPR) of size-controlled NDAs fabricated using AAO masks has not been much studied. In this study, we report on the improved preparation method and utilization of an ultrathin AAO mask for the fabrication of 2D plasmonic metal NDAs. The greatest challenge in preparing an AAO mask is to control the pore diameter and to make it reproducible. AAO masks with size-controlled pores were reproducibly prepared using a two-step chemical wet etching method. Ag NDAs with different dot diameters (42, 60, and 80 nm) and Ag, Cu, and Au NDAs with dot a diameter of 80 ± 5 nm were fabricated on indium tin oxide glass substrates using AAO masks. The wavelengths corresponding to LSPR of 2D metal NDAs were investigated using ultraviolet–visible spectroscopy. Our results show that AAO masks with tunable pores can be used as shadow masks for the fabrication of 2D plasmonic NDAs.
