“…We emphasize that the presence of PVP in the growth environment is a necessary condition for the formation of prisms in the mixture Eg + G + Et + HAuCl4 [3,15,16]. This conclusion is confirmed by our previous studies [17][18][19]. We have identified that the surface of NPRs and NPs has been coated with a PVP layer.…”

“…We have identified that the surface of NPRs and NPs has been coated with a PVP layer. Moreover, a variety of shapes of these particles took place due to the specific adsorption of gold ions, PVP molecules, and PVP-Au complexes on the MoS2 surface [19]. It was found that the size and shape of the particles are affected by the molecular weight of the polymer, the concentration ratio of PVP and HAuCl4, and the time of synthesis [12,[20][21][22].…”

Here we report on the synthesis of plasmonic gold nanostructures, preferably nanoprisms, having clean surface. They were grown on the molybdenum disulfide (MoS2) modified with polyvinylpyrrolidone (PVP). The synthesis of such nanostructures was carried out in two stages. At the first stage, a modified MoS2/PVP surface was obtained, and then gold nanoprisms were synthesized on this surface in growth solution without PVP. To confirm the cleanliness of nanoprisms, scanning electron microscopy and atomic force microscopy, as well as micro-Raman spectroscopy were applied.

“…Vacuum methods of obtaining highly disperse arrays have a number of advantages of chemical technologies [10][11][12] which are widely used now. Thus, the condensation of samples and their dispersion under high vacuum conditions makes it almost completely possible to dispose of uncontrolled impurities that have a primary influence on structures with a high surface fraction.…”

The results of research devoted to formation of ordered arrays of particles during melting process of tin films on amorphous carbon substrate are given in the present work. Using scanning electron microscopy the histograms of particle size distribution are constructed for films of different mass thickness. The size dependences of the most probable radius of particles, which are formed during the melting process, and the half-width values of the corresponding histograms are obtained as well. The excess energy, which provides a decomposition of the initially continuous film into separate islands, is estimated and its size dependence is built. As shown, the melting process of films, which are condensed in island structures, provides larger filling coefficients in comparison with the melting process of initially continuous films.
