Change in Stoichiometry of ZnS Nanoparticles from the Energy of Action to Nano- and Femtosecond Laser Radiation

In this paper, experiments on laser ablation of ZnS in atmospheric air using laser pulses with different energies and durations have been carried out. In the process of ablation processing, zinc sulfide nanoparticles with different stoichiometric ratio of elements were obtained. By varying the parameters, it is possible to control changes in the size of nanoparticles and their composition. As a result of studies of synthesized nanoparticles, Raman scattering spectra, energy dispersion analysis results, and images of deposited nanoparticles were obtained. Conclusions are drawn about the suitability of nanopowder synthesis approaches for the subsequent production of stable colloidal solutions.
