摘要：
Provided is a mechanoluminescent material which can radiate near-infrared light. The mechanoluminescent material includes an aluminate co-doped with Eu2+, Cr3+, 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 MAl2O4 (provided that, M is any of Mg, Ca, Sr, or Ba) and Eu2+, Cr3+, 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%.
