“…The low-emissivity coatings of dielectricmetal-dielectric multilayer structure have been widely investigated such as ITO/Ag/ITO, TiO2/Ag/TiO2, SnO2/Ag/SnO2, ZnO/Ag /ZnO and ZnS/Ag/ZnS ( Chiba & Kaminishi, 2008;Dhar & Alford, 2013;Mungchamnankit et al, 2014;Kim et al, 2016). However, the Ag atoms can react with the oxygen of dielectric layer at high temperature and lead to poor-low-emissivity, corrosion resistance, chemical durability and thermal stability (Chokboribal et al, 2021;Kulczyk-Malecka et al, 2014;Loka, Yu & Lee, 2014).…”

AlN and Ag thin films were deposited independently on the Si(100) wafers and glass slides by sputtering techniqueat various times to find the optimum deposition times for coating AlN and Ag films layers. The results obtained fromglazing-incident X-ray diffraction (GIXRD), field-emission scanning electron microscopy (FE-SEM), and transmittancemeasurements showed that the optimum deposition time for coating AlN and Ag film layers were 40 min and 15 scorresponding to the film thickness of 46.7 and 19.6 nm, respectively. The optimum deposition times were used forcoating AlN and Ag films in the multilayer AlN/Ag/AlN film stack. Then, the multilayer AlN/Ag/AlN film stack wasdeposited on the glass slide for transmittance measurement and a test glass plate with a size of 10 cm x 10 cm for infraredprotection testing. The average solar transmittances in the visible range ( = 380-780 nm) and in the near infrared range( = 780-2,000 nm) were found to be 48.05 and 15.17%, respectively which are comparable with those of a commercialglass.

“…However, in SERS bio-experiments one needs to assure the reliability of measurements, since the substrates with noble metal NPs made in different ways can behave differently in biological solutions and react with biological objects. One of the most promising SERS substrates are nanoisland films of noble metals, which can be made by depositing or growth of metal nanoparticles on the surface [8,9], annealing of a thin metal film [10,11] or out-diffusion of metal from glass substrates [12,13]. An important feature of such substrates, which makes them attractive for use, is their uniformity, which provides uniform enhancement of Raman signal over the substrate, and fabrication reproducibility [9,14].…”

We investigated the stability of silver nanoisland films, which were formed on glass surface by the method of out-diffusion, in biocompatible buffers and the applicability of the films in surface enhanced Raman scattering (SERS). We have shown that silver nanoisland films are stable in one of the most widespread in biological studies buffer—phosphate buffer saline (PBS), and in 1:100 water-diluted PBS, in the PBS-based buffer, in which NaCl is replaced by the same amount of NaClO4, and in acidic phosphate buffer. At the same time, the replacement of NaCl in PBS by N(CH3)4Cl leads to the degradation of the nanoislands. It was shown that after exposure to PBS the nanoisland films provided a good SERS signal from a monolayer of 1,2-di(4-pyridyl)ethylene (BPE), which makes silver nanoisland films promising for biosensor applications. Additionally, in our experiments, we registered for the first time that silver nanoparticles formed in the bulk of the samples dissolved after exposing to PBS, while nanoislands on the glass surface stayed unchanged. We associate this phenomenon with the interaction of ions contained in PBS solution with silver, which results in the shift of corresponding chemical equilibrium.
