Abstract The selection of mechanoluminescent materials is often unpredictable and arbitrary, posing new challenges for the application high‐performance mechanoluminescence (ML). Materials with exceptional photoluminescence (PL) properties generally possess highly efficient carrier radiative transitions. Investigating how to induce ML in these can provide perspectives on materials. Here, a universal strategy multicolor via energy transfer by ultraviolet material Ca 9 Al(PO 4 ) 7 :Ce 3+ (CAPC) proposed. Multicolor be regulated through isomerization acceptors. In CAPC@energy acceptor@polydimethylsiloxane composite system, relies simple (reabsorption) mechanism, rather than complex between excited states ions. Using this strategy, certain PL develop ML, transitioning from nonexistent present or weak strong. Additionally, color tuned adjusting composition ratio donor acceptor.

Controllable Modulation of Trapped Carriers in Mechano/Thermo Dual‐Responsive Particles for Advanced Stress‐Encoded Information Storage

Laser & Photonics Review, Journal Year: 2024, Volume and Issue: 18(10)

Published: May 16, 2024

Abstract Mechanoluminescence (ML) is a fascinating phenomenon with diverse applications in pressure sensing, damage detection, and stress distribution visualization. However, most ML materials exhibit instantaneous photon emission that requires real‐time recording photodetector, thereby circumscribing their applicability predominantly to stress‐sensing scenarios. In this work, novel method introduced for non‐real‐time sensing utilizing Li 0.1 Na 0.9 NbO 3 :Pr 3+ phosphor, which allows the retrieval of location intensity even 20 days after event. The influence heat on trap depth analyzed using thermoluminescence (TL) measurements, it proved both release captured electrons same traps. Leveraging intricate competition between mechanical thermal detrapping processes, information can be accessed through TL imaging. Furthermore, an algorithm proposed based authenticate information. This research not only advances fundamental understanding phenomena but also introduces approach such as mechano‐history indicators, security papers, advanced data storage systems.
