Abstract Mechanoluminescence (ML) materials have shown great promise in stress sensing, structural monitoring, information encryption etc., but are primarily based on crystalline material with limited processability, environmental stability, and optical transparency, which seriously hinder their applications. Here, a highly transparent Mn 2+ ‐doped amorphous glass system significant ML properties is designed. A composition modulation strategy proposed to engineer defects within the network structure, ensures more numerous activate of . Under repeated charging–discharging cycles, samples present remarkable repeatability recovery performance, intensity demonstrates zero‐quenching performance after being placed various solutions for 14 days. Combined Raman, EPR spectra, TL experiments, inherent relationship between traps clarified, where oxygen vacancies responsible generation ML. Based ideal high transparency designed glass, application prospects identification detection evaluated. This work provides design principle accelerate development toward versatile photonic

Abstract Mechanoluminescent (ML) materials are promising for applications in structural health monitoring, biomedicine, stress sensing, and distribution visualization due to their ability emit light without external circuits. However, current ML face challenges, including limited luminescent colors, high raw material costs, toxicity, lack of emissions the invisible spectrum. To overcome these Ca 2 P O 7 (CPO) is selected as matrix its excellent piezoelectric properties, low cost, biocompatibility. CPO doped with various ions (X, X = Ce 3+ , Eu 2+/3+ Tb Dy Mn 2+ Sm ) achieve emission bands CPO:X across a wide range wavelengths UV, blue, green, yellow red. Unlike traditional trap‐controlled materials, does not require UV pre‐irradiation exhibits remarkable self‐recovery properties. First‐principles density functional theory (DFT) calculations confirmed that an ideal self‐recovering materials. Based on several practical devices designed, fencing competition scorekeeper, wearable flexible skin, protective dental crown layer. These innovations offer new directions development application

Abstract Mechanoluminescence (ML) elastomer shows tremendous potential for the next generation of flexible displaying, imaging, and sensing devices. However, inadequate repeatability cyclic stability are current bottlenecks. In this work, a solid‐solution strategy is reported to regulate interfacial interactions ML elastomer, in which (Ca,Ba) 5 (PO 4 ) 3 Cl:Eu solid solutions polydimethylsiloxane (PDMS) employed, respectively. The results suggest that can effectively modulate energy position valence band charge density distributions lowest unoccupied band, as well triboelectrification. Consequently, performance composite terms intensity, spectral characteristic, has been significantly improved. Particularly, optimum CaBa Cl:Eu/PDMS exhibits stable repeatable over 20 000 cycles under various rapid continuous stretching conditions. This work not only provides highly cyclically but also clarifies intrinsic physical principles, showing high guiding significance future design applications.
