In recent years mechanoluminescence (ML) materials attracts attention. New ML material SrA12O4^Eu with remarkable upgrade in ML intensity is developed by Xu et.al. It emits an intensive and repeatable ML during elastic deformation without destruction. In this study, influence of the stress exerted on the luminescence characteristic of ML powder mixed with epoxy resin was investigated. Moreover, realization of visualizing of stress distribution was also considered.
