“…As a rule, surface-enhanced Raman spectroscopy uses substrates whose surface is modified with silver, gold, or copper nanostructures with different microstructural characteristics [ 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 ]. Recently, much of researchers’ attention has also been directed toward studying the processes of obtaining composite SERS-active films—Ag@nanoAu [ 4 ], Ag nanocubes@poly(dimethylsiloxane) [ 13 ], Ag/TiO 2 [ 14 ], MoO 3-x /Ag [ 15 ], b-cyclodextrin-modified Ag [ 16 ], Au/Ag and Au/Ni [ 7 , 17 ], Ag particles/Ag-Zr alloy [ 18 ], Mo-Ag [ 19 ], Ag/AgBr/ZnO [ 20 ], ZnO/Ag 3D nanocomposites [ 21 , 22 ], ZnO/Au [ 23 ], MnO 2 /Au [ 24 ], Au/ZrO 2 [ 25 ], rGO-Ag [ 26 ], or Ag/C [ 27 ]. In some cases, metal-free SERS substrates, particularly based on MoS 2 , are proposed [ 28 ].…”

In this article, a facile, one-step method for the formation of silver thin-film nanostructures on the surface of Al2O3 substrates using the hydrothermal method is proposed. The dependence of the SERS effect intensity of the formed films during the detection of methylene blue (MB) low concentrations on the synthesis conditions, additional temperature treatment, and laser radiation wavelength (532 and 780 nm) in comparison with similar dye films on commercial SERS substrates is shown. The detection limit of the analyte used for the indicated lasers is estimated. The effect of the synthesis temperature on the particle size, crystal structure, and microstructure features of the obtained thin films based on silver nanoparticles is demonstrated. Using spreading resistance microscopy, the interface between the substrate and Ag particles is studied, and the dependence of the size of the corresponding gap between them and the nature of microstructural defects on the parameters of hydrothermal treatment of reaction systems in the presence of Al2O3 substrates is shown. As a result of the study, the factors associated with the properties of the obtained SERS substrates and the parameters of recording the spectra, which affect the amplification factor of the spectral lines intensity of the analyte, are revealed.
