“…It has been reported that even plastic teabags can release billions of nanoparticles (Hernandez et al, 2019). Other industrial sources include the direct production of NPs and feedstocks used for the manufacture of plastics (Yoshino et al, 2012;Phuc et al, 2014).…”

“…The first one is that it strongly depends on the shape, size and the arrangement of the nanostructures. This characteristic attracts a lot of researches to fabricate various nanostructures such as nanodots [9][10][11][12], nano-rods [13][14], and nano wires [15][16] with various configurations in order to improve their LSPR property. The second characteristic is that LSPR strongly affected by the refractive index of the environment surrounding metallic nanostructures.…”

“…Metallic nanostructures are generally fabricated by the top-down processes such as electron beam lithography (EBL) [19][20], focus ion beam (FIB) [21] or by the bottom-up processes such as like the self-organization methods [22][23] and anodic aluminum oxide (AAO) template [24] or by hybrid processes developed by our group [9][10][11][12]25].…”

In this research, an effective method to fabricate various metallic nanoand micro structure patterns is developed by combination of chemical stamping and selective peeling off technique. The feasibility of the process is experimentally studied and demonstrated. In this paper, the authors present the effects of the chemical treatment on the substrate surface on the formation of the nanodots array and its absorbance property. The results show that the chemical treatment by dropping Acetone solution on the quartz glass substrate strongly affects the morphology and absorbance property of the nanodots array. With the Acetone treatment on the substrate, the nanodots become smaller and more uniform in size through thermal dewetting process. Simultaneously, it results in blue shifted of the absorbance peak and enhancement of the absorbance peak intensity. The improvement of the optical property of the nanodots array is useful for plasmonic solarcell and bio sensing applications.

“…Introduction: Array of Au NPs (gold nanoparticles) is a much sought after structure having a wide range of applications in photovoltaics [1], surface enhanced fluorescence [2], bio sensing [3], label-free visualisation of living cells [4], magnetic memory and so on. Different processes are available to fabricate an array of Au NPs such as focused ion beam fabrication [5], femtosecond laser irradiation [6], thermal dewetting [7][8][9], nanoplastic forming with thermal dewetting [10][11][12][13] and so on. However, most of these processes results in random sized nanoparticles (NPs) and their position are also random and/or it is difficult to achieve over a larger area.…”

Ordered arrays of substrate supported gold nanodots are fabricated on c-Si as substrate. Electron beam lithography followed by DC sputter coating was used for the fabrication of ordered gold nanodots over a 1 × 1 cm 2 area on c-Si substrate. The fabricated ordered arrays of gold nanodots were characterised through the reflectance spectra. Reduction of 60.67% in reflectance was exhibited by ordered gold nanodots when compared with bare c-Si. For comparison, a random gold nanoparticle array of approximately same particle size was fabricated and the reflectance was compared with the ordered array. It was found that the reflectance of ordered array is 52.27% less than that of random array. This route is suitable for fabrication of large area ordered gold nanodots which has applications in photovoltaic industry.
