Growth of Gold Nanostructures on the MoS2 Surface Modified with Polyvinylpyrrolidone

Abstract

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.
