Abstract Elastomeric mechanoluminescence (EML) materials capable of generating luminescence during elastic deformation are promising for many practical applications in modern technologies. Among them, copper- or manganese-doped zinc sulfide (ZnS) in a polydimethylsiloxane (PDMS) matrix has emerged as the most efficient EML material by virtue of its intense EML intensity. However, it is insufficient to trigger abundant electron entrapments and activate high energy blue emission under weak mechanical stimuli ( e = 10%). Furthermore, various application prospects of a series of proof-of-concept optical devices such as handwriting input, gesture sensing, and encrypted anti-counterfeiting are successively demonstrated. This feasible technique provides a general platform to broaden color expression under weak mechanical stimuli, which could inspire the fabrication of various novel applications.

用于可视化传感和防伪的硫化锌基机械发光弹性体的有效颜色控制

摘要 能够在弹性变形过程中产生发光的弹性机械发光 (EML) 材料在现代技术中具有许多实际应用前景。其中，聚二甲基硅氧烷 (PDMS) 基质中的铜或锰掺杂硫化锌 (ZnS) 凭借其强烈的 EML 强度已成为最有效的 EML 材料。然而，在弱机械刺激（e = 10%）下，不足以触发大量电子俘获并激活高能蓝色发射。此外，还陆续展示了手写输入、手势感应、加密防伪等一系列概念验证光学器件的各种应用前景。这种可行的技术为在弱机械刺激下拓宽颜色表达提供了一个通用平台，
