Investigation of Energy Traps and Phosphorescence in Zinc Silicate Phosphors by Photostimulated Emission

View publication

Abstract

The manganese activated zinc silicates doped with or without arsenic are investigated using photostimulated luminescence technique in addition to conventional photoluminescence and phosphorescence measurements. The experimental results provide information about the energy levels of the Mn++ and the traps and how they interact during the luminescence process. Based on conclusions deduced from experimental data, a physical model is proposed for interpreting the zinc silicate luminescence and phosphorescence with some clues on the role of the arsenic doping and its effect on phosphorescence. © 1980, The Electrochemical Society, Inc.
