Interdiscipline between optoelectronic materials and mechanical sensors:Recent advances of organic triboluminescent compounds and their applications in sensing

摩擦发光,也称为机械发光,是一种特殊的光学现象,指特定的有机或无机材料在受到外力作用(如挤压、变形、劈裂、振动等)时的发光行为。无机摩擦发光材料在传感领域已经显示出巨大的应用潜力,如应力传感、损伤检测等。然而,有机摩擦发光材料的摩擦发光机理及其应用还需要进一步推动。在本文中,我们总结了有机摩擦发光材料的发展历史和摩擦发光的机理,以及在传感领域中的应用。同时,受到现有无机摩擦发光材料应用的启发,我们对有机摩擦发光材料在应力传感器、运动监测、应力成像分布、裂纹扩展可视化、结构诊断等领域的应用前景进行了展望。

Triboluminescence,also as known as mechanoluminescence,is an attractive optical behavior that means the light emitted from specific organic and inorganic materials when they are subjected to external forces,such as crushing,deformation,cleaving,vibration.Inorganic triboluminescent materials show great potential for applications in sensing,such as stress sensing,damage detection.However,the triboluminescent mechanism of organic materials should be pushed further as well as their application.In this review,we summarized the history of development and possible mechanism of organic triboluminescent materials,and discussed various applications in sensing field.At the same time,inspired by the existing research progress in inorganic triboluminescent materials,we proposed the flourishing development prospects of organic triboluminescent materials in stress sensors,movement monitoring,imaging stress distribution,visualization of crack propagation,structural diagnosis,and other fields.
