Abstract: In this work, laser spectroscopy was used to study reverse microemulsions, in which the reaction of ZnS nanoparticle synthesis was carried out. The sizes of the synthesized nanoparticles do not exceed 5 nm. As a result of studying the processes in the reaction medium, it was found that the band of stretching vibrations of HS$^-$ ions in the region of 2568 cm$^{-1}$ is an identification sign of the synthesis of nanoparticles: by its intensity it is possible to determine the stage and completion of the ZnS synthesis.

Keywords: nanoparticle synthesis, nanoreactors, laser diagnostics, Raman spectroscopy, reverse microemulsions.
