Featured with specific relationship between luminescence intensity and stress, mechanoluminescence (ML) has shown great application potential in stress sensing. However, the uncertainty in acquisition of absolute ML intensity may cause significant error in ML-intensity-based stress sensing. A ratiometric ML scheme has been recently proposed as an alternative solution to circumvent such problem. In this paper, a novel strategy based on a lanthanide structural probe is demonstrated to realize the ratiometric ML for stress sensing, where the stress-induced change in local site symmetry leads to the establishment of the relationship between the ML asymmetry ratio of the structural probe and the applied stress. This strategy offers a brand-new design solution toward ratiometric ML aiming at improving the reliability of stress sensing.

比率机械发光应力传感:一种基于结构探针的策略

机械发光 (ML) 具有发光强度与应力之间的特定关系,在应力传感方面显示出巨大的应用潜力。然而,获取绝对 ML 强度的不确定性可能会导致基于 ML 强度的应力传感出现重大错误。最近提出了比例 ML 方案作为规避此类问题的替代解决方案。在本文中,展示了一种基于镧系元素结构探针的新策略,以实现用于应力传感的比率 ML,其中应力引起的局部位置对称性变化导致结构探针 ML 不对称比率之间关系的建立和施加的应力。该策略为比率 ML 提供了一种全新的设计解决方案,旨在提高压力传感的可靠性。
