RESEARCH ON SOLID STATE RADIATION-INDUCED PHENOMENA

Abstract

Luminescent and photoconductivity measurements (the latter using a.c. impedance methods) were performed on a ZnS:Cu and ZnS:Ag phosphor under X-Ray excitation. These measurements were made during the rise, equilibrium, decay, and glow periods as well as under various conditions of infrared irradiation. These results clearly show that the usually accepted phosphor model (SchonKlassens) must be appreciably modified. Two series of ZnS/Cu:Cl phosphor powders are prepared; one series with the careful exclusion of O2, the second with O2 added to atmosphere during firing. All other preparative conditions are identical. Luminescence spectra, lumin scent glow curves, I.R. effects and electroluminescence of each phosphor are investigated.
