The work carried out studies of highly dispersed powder ZnS:Mn obtained by the method of self-propagating high-temperature synthesis [1]. The concentration of Mn impurity in the samples under investigation was 1 wt%. Sulfur and zinc were taken for synthesis in the ratio close to stoichiometric.  The spectra of photoluminescence were measured at a temperature of 1.6 K, the magnetic field changed from 0 T to 5 T. Electronic microscopic studies of ZnS:Mn, and were carried out using scanning electron microscopy (SEM) according to the data obtained, the average particle size of fine ZnS:Mn was ~50 nm. The influence of a magnetic field on the redistribution of the intensity of photoluminescence bands of ZnS:Mn is shown. With an increase in the magnetic field induction, a significant decrease in the intensity of the band caused by the manganese impurity occurs. In this case, the intensity of the self-activated luminescence band does not change significantly
