压电光子效应是压电特性和光激发之间的耦合，其中应变诱导的压电势调制和控制相关的光学过程。具体来说，金属离子作为活化剂能够响应光激发和随后的光发射，通常也称为机械发光，特别是压电材料的压电发光。这些现象有助于理解材料的基本原理和设想广泛的器件应用。本文简要介绍了压电光子学的物理机制，包括压电发光。描述了用于演示压电效应的选定的宿主材料和金属离子激活剂。我们提供了由机械刺激引发的光发射的统一轮廓和最近的原型演示。基于这些材料的器件具有远程检测、无损分析和可重复性等优点，因此它们在应力传感、结构健康诊断、三维手写、磁光传感、能量收集、生物医学、新型光源和显示等领域具有广阔的应用前景。
The piezophotonic effect is the coupling between piezoelectric properties and photoexcitation, where strain-induced piezopotential modulates and controls the relevant optical process. Specifically, metal ions as activators are capable of responding to photoexcitation and subsequent emission of light, also called mechanoluminescence, in general, and piezoluminescence specifically for piezoelectrics. These phenomena are helpful for understanding the materials fundamentals and conceiving widespread device applications. In this article, we briefly introduce the physical mechanisms of piezophotonics, including piezoluminescence. Selected host materials and metal-ion activators are described for demonstrating the piezophotonic effect. We provide a unified profile and recent prototypical demonstrations of light emission triggered by mechanical stimuli. The devices based on these materials offer the advantages of remote detection, nondestructive analysis, and repeatability, hence they are promising candidates for applications in stress sensing, structural health diagnosis, three-dimensional handwriting, magnetic-optical sensing, energy harvesting, biomedicine, novel light sources, and displays.
