The experimental results on the synthesis of ZnS:Мn nanoparticles, as well as the study of their structure and optical and photoluminescence characteristics, are reported. The ZnS:Мn nanoparticles and thin films on silicon and glass substrates are grown via hydrochemical deposition from the solution containing thiourea, zinc chloride, manganese chloride, and dimethyl sulfoxide. The internal structure of the samples is probed via X-ray diffraction (XRD), atomic force microscopy (AFM), and scanning electron microscopy (SEM). The spectral dependence has allowed a determination of the bandgap width in ZnS:Мn nanoparticles. It is found the photoluminescence peak intensity increases with the enlargement of nanoparticles.
