The variations in the glow curve and the luminescence spectrum of ZnS and ZnO phosphors after alpha irradiation were investigated. After the irradiation no new glow curves were found. Possibly deep traps produced by irradiation participated only as quenching centers. The Zn and S defects formed in the phosphor by irradiation were calculated. Aiter irradiation of green- luminescent ZnS(Cu) phosphors, a blue emission band was prominent. This effect was traced beck to the origin of blue-luminescent Zn/sup 2+/ defects. (trauth)
