Phosphorescence light decay curve from mechanoluminescence material subjected to hydrostatic load

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 equipment to measure the time dependence of the emitting light intensity from the liquid containing the elasticoluminescent material (SrAl2 04 :Eu2+ powder) under hydrostatic load is proposed.
