Deep-Learning Enhanced SrAl2O4: (Eu2+, Dy3+, Nd3+) Mechanoluminescence Film for Distributed Perception of Mechanical Deformation and Fracture (Advanced Optical Materials 17/2025)

Abstract

Mechanoluminescence

The cover image illustrates a strontium aluminate-based material engineered through an element co-doping strategy. The derived thin film exhibits exceptional sensitivity to surface deformations and microcrack propagation. By integrating deep learning algorithms with real-time strain data, this system enables dynamic, high-resolution reconstruction of stress fields under complex mechanical loads. For details, see article number 2403516 by Qiangqiang Zhang and co-workers.
