Abstract

Piezoluminescence, which is also called elasticoluminescence, is a form of mechanoluminescence (ML) during the elastic deformation, which has attracted considerable attention because it can be repeatedly used for mechano-optical conversion. Elastic ML offers the advantages of wireless detection and nondestructive analysis, making it a promising candidate for various applications. This talk will discuss the physical mechanisms of mechanoluminescence, materials, and applications. Selected host materials and metal-ion activators are used for demonstrating the fundamentals. These materials offer the advantages of remote detection, nondestructive analysis, and repeatability, they are promising for applications in stress sensing, structural health diagnosis, energy harvesting, biomedicine, novel light sources, and displays.
