Abstract: Provided is a mechanoluminescent material which can radiate near-infrared light. The mechanoluminescent material includes an aluminate co-doped with Eu 2+ , Cr 3+ , and an ion or ion cluster of at least any one rare earth metal element selected from Sc, Y, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, or Lu. In addition, in the mechanoluminescent material, the aluminate is an aluminate represented by Formula MAl 2 O 4 (provided that, M is any of Mg, Ca, Sr, or Ba) and Eu 2+ , Cr 3+ , and the ion or ion cluster of a rare earth metal element are co-doped at a concentration at which M in the aluminate is substituted by from 0.25 to 10%.
