Near infrared mechanoluminescence (NIR-ML) materials have attracted the attention of researchers due to their unique advantages, such as high resistance bright-field interference and higher penetration depth into biological tissues. However, reported NIR-ML are mainly rare-ion-activated narrow-band emitters. In this work, we report a material BaGa12O19:Cr3+ by solid state reaction method. Broad NIR ML (650-1000 nm) is observed at lower force loads (12 N), which based on Cr3+ ion's multi-lattice site occupation. After heat treatment 573 K for 20 min, still maintains 84.4% its intensity. Furthermore, intensity also significantly improved after UV pre-irradiation. Due defective piezoelectric photonic effect, has great self-recoverable properties even in absence sunlight irradiation. Finally, rate reached 66.97% tissues, suggests potential prospects biostress detection towards bio-imaging applications.

Abstract Mechanoluminescence (ML) materials have shown broad application potentials in stress sensing and structural monitoring due to situ, real‐time monitoring, low trigger threshold. However, the accurate detection of distribution inside machinery still faces certain challenges. Based on a flexible ML film prepared by SrAl 2 O 4 : Eu 2+ , Dy 3+ phosphor polydimethylsiloxane, this paper proposes “stress difference” strategy monitor mechanical structure. By applying different loads recording linear relationship between intensity load, local engine bearing can be measured. comparing difference I PersL specific machine is successfully inferred. This study provides new ideas for sensing, which may open up an innovative method structures.

Abstract Near‐infrared mechanoluminescent (NIR ML) materials have attracted attention due to their advantages, such as in situ and real‐time monitoring of biomechanical information vivo. However, most ML are focused on the UV–vis light range, which limits potential applications biological field. In this work, a broadband NIR material Ca 2 YGa 3 Ge O 12 : 0.10Cr 3+ (CYGGG: ) is successfully prepared by chemical co‐substitution Cr heavy doping. Density functional theory (DFT) calculations used determine type defects material, composite formed interstitial oxygen (i ′′) antisite (Ca Y ′ ‐ °) mostly dominate ML. ions act electronic bridges regulate energy levels, becoming key turning Nd ion's Finally, based excellent properties CYGGG: , 0.01Nd composites can penetrate pork tissues different compositions/thicknesses under stress loads. Potentially, work tries realize tissue imaging, providing new way for application materials.
