Abstract

The project aims to prepare thin films of MoS2 with gold nanoparticles, through the liquid/liquid interfacial method, their deposition on solid substrates (SiO2 or PET) and the study of their potential as SES substrate. Specifically, films with 3 different proportions between the components will be prepared, and three different molecules (rhodamine 6G, 4ATP and caffeine) will be studied, at three different laser energies, in different solution concentrations. Different forms of analysis, data collection and interpretation of results will also be studied. (AU)
