Dual‐Window Broadband Near‐Infrared Mechanoluminescence in MgO‐Based Phosphors

emission, whereas mechanical excitation directly activates their low-lying levels. These insights unify mechano-to-photon conversion in centrosymmetric oxides and provide design principles for broadband, durable, and environmentally adaptive ML materials, advancing applications in multimodal sensing, structural health monitoring, and noninvasive biomechanical imaging.
