最近，我们提出了一个主题的应力分布可以可视化，通过利用一种新的机械发光现象，可以通过施加机械应力产生强烈的可见光发射。由于在弹性区发光强度与应变能随时间的变化成正比，我们称之为弹性发光。为了在应力分布的可视化中实现高空间分辨率，我们的目标是开发强弹性发光纳米颗粒，例如α-SrAl 2 O 4：Eu（单斜相）的受控结构。本文将对纳米粒子的制备、性质及应用进行综述。
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.
