摘要

Visualized self-powering stress sensing can be realized via mechanoluminescence(ML) materials due to their ability to convert mechanical stimulate intooptical signals. Traditional ML-intensity-based stress-sensing is susceptibleto errors caused by unpredictable measurement circumstances, which canbe significantly improved by a recently developed ratiometric ML sensingstrategy. Herein, a series of dual-activator phosphatic materials are designedto realize ratiometric ML. The linear dependence of mechanoluminescenceintensity ratio (MLIR) on the applied force leads to an obvious variation in MLemission color upon different applied stress, and therefore enables a colorresolvedvisualization of stress-sensing. Specifically, an evaluating systemis established to quantify the stress-sensing performance of ratiometric MLmaterials for the first time, which is considered to be an important steptoward the practical application of ratiometric ML-based stress-sensing.
