“…[ 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 ] In particular, by using the visible luminescent signals as the medium, ML could enable in situ, remote, distributed and visualized mechanics sensing for complex and irregular interfaces.

Nevertheless, most of the current ML materials intrinsically exhibit instantaneous luminescence with a short lifetime ranging from nanoseconds (ns) to microseconds (ms).…”

Persistent mechanoluminescence (ML) with long lifetime is highly required to break the limits of the transient emitting behavior under mechanics stimuli. However, the existing materials with persistent ML are completely trap‐controlled, and a pre‐irradiation is required, which severely hinders the practical applications. In this work, a novel type of ML, self‐charging persistent ML, is created by compositing the Sr3Al2O5Cl2:Dy3+ (SAOCD) powders into flexible polydimethylsiloxane (PDMS) matrix. With no need for any pre‐irradiation, the as‐fabricated SAOCD/PDMS elastomer could exhibit intense and persistent ML under mechanics stimuli directly, which greatly facilitates its applications in mechanics lighting, displaying, imaging, and visualization. By investigating the matrix effects as well as the thermoluminescence, cathodoluminescence, and triboelectricity properties, the interfacial triboelectrification‐induced electron bombardment processes are demonstrated to be responsible for the self‐charged energy in SAOCD under mechanics stimuli. Based on the unique self‐charging processes, the SAOCD/PDMS further exhibits mechanics storage and visualized reading activities, which brings novel ideas and approaches to deal with the mechanics‐related problems in the fields of mechanical engineering, bioengineering, and artificial intelligence.

“…1,[5][6][7][8][9][10][11] However, quite a few problems in ML materials have to be solved, for example, weak ML intensity and limited ML spectral range, especially in the UV spectral band. 12 Extending ML to the UV band is of great significance for both basic scientific research and practical applications.

“…In another case, Tu et al realized the stress-dependent ML color manipulation by adopting mixture of two ML phosphors (Ca 8 Mg 3 Al 2 Si 7 O 28 : Eu 2+ and Sr 8 Mg 3 Al 2 Si 7 O 28 : Eu 2+ ) with different ML sensitivity. [5] Further exploration of more ML phosphors with stressdependent ratiometric emission requires systematic knowledge on the origin of diversity in ML response of different luminescence centers to stress. Based on the different response of luminescence dynamics of activators to the stress-induced change in local crystal field strength, very recently, our group proposed a ratiometric dual-activator ML strategy to realize the stress-sensitive color variation.…”

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.
