The development of high-performance self-recoverable near-infrared (NIR) mechanoluminescent materials is crucial for advancing applications. In this work, we presented a self-recoverable NIR mechanoluminescent material, platelike SrAl<sub>12</sub>O<sub>19</sub>, through singly doped with Cr<sup>3+</sup> and co-doped with lanthanide ions (Nd<sup>3+</sup>, Yb<sup>3+</sup>, Er<sup>3+</sup>) in one step. By modulating the Cr<
