Development of Elastico-Luminescent Nanoparticles and their Applications

Abstract

Recently we have proposed that stress distribution of a subject can be visualized by utilizing a novel mechanoluminescence phenomenon that can give intense visible light emission by application of mechanical stress. As the luminescence intensity is proportional to the time-variation of strain energy in the elastic region, we call it elastico-luminescence. In order to realize a high space resolution in such visualization for stress distribution, we aim to develop strong elastico-luminescent nanoparticles, such as a controlled structure of α-SrAl2O4:Eu (monoclinic phase). The processing of the nanoparticles, the property and the applications will be reported in the present work.
