We report nitrogen plasma modification of the ZnS: Cu, Br electroluminescence phosphor. Modification resulted in 30% improvement of ZnS: Cu, Al EL brightness at 220V drive. In the same time emission peak shifted of from 486 to 504nm due to increase of relative intensity of green band in EL spectrum. Thus plasma treatment is a perspective method for the control of EL brightness and spectra of ZnS phosphors.
