N2 - The effect of γ-ray photons and electron beams on electroluminescence of the ZnS:(Cu, Br) and ZnS:(Cu, Al, Br) phosphors is studied. Irradiation of both samples with γ-ray photons and of the ZnS(Cu, Br) sample with electrons makes it possible to increase the emission intensity by 20-35% at the optimal radiation dose of 5-10 Mrad. In this case, the relative intensity of the green-emission band increases in the electroluminescence spectra of all samples, presumably due to dissociation of the CuI-CuZn and BrZn-V Zn donor-acceptor pairs. Thus, irradiation makes it possible to control the intensity and spectrum of phosphors' emission, which can be used for nonchemical lithography of luminescent layers.
