The Formulation of emission intensity attenuation by phosphorescence characteristics of stress-stimulated luminescent materials

Abstract

The elasticoluminescent materials emit with respect to stress and have the phosphorescence with the gradually decreasing emitting light. In this study, we present the formula to characterize the phosphorescence light emitting by considering the absorption of the emitted light. The time dependence of the emitting light intensity from the epoxy reign specimen doped with the elasticoluminescent material (SrAl2 O4 :Eu2+ powder) is measured, and compared to the present formula. The measured data and the calculated data are in good agreement.
