Mechanoluminescence and Mechanical Quenching of Afterglow Luminescent Particles for Wearable Photonic Display Seong-Jong Kim, Fan Yang, Ho Sang Jung, Guosong Hong, and Sei Kwang Hahn*   Journal : Advanced Functional Materialspublished : 09 February 2024   AbstractOptical properties of afterglow luminescent particles (ALPs) in mechanoluminescence (ML) and mechanical quenching (MQ) have attracted great attention for diverse technological applications. However, these unique phenomena need to be more clearly explained for the specific photonic application. Here, ALPs are designed for the development of a wearable andrewritable photonic display system as a communication toolbox under dark conditions or underwater environments with limited communication. This display system demonstrates long-lasting MQ after short ML along the handwritten trajectories with mechanical pressure and the written content can be easily erased by short UV light irradiation, preserving the systeminteg..
