description The invention belongs to the technical field of mechanoluminescent materials, and discloses a mechanoluminescent material capable of realizing instant self-recovery without pre-irradiation and luminescence and a preparation method thereof. The general formula of the mechanoluminescent material is LiGa5(1-x) O8: 5(x)Cr, the crystal structure belongs to a cubic crystal system, and the active ionis Cr. According to the method, the molar ratio of Li to Ga to O to Cr is 1: 5(1-x): 8: 5x, and x is larger than or equal to 0.04% and smaller than or equal to 0.24%; The preparation method comprises the following steps of: respectively weighing compound raw materials containing lithium, gallium and chromium, uniformly mixing, pre-sintering at 600-1000 DEG C in an oxidizing atmosphere, and carrying out high-temperature treatment at 1250-1550 DEG C in the oxidizing atmosphere to obtain the mechanoluminescence fluorescent material. The mechanoluminescence material disclosed by the inventioncan realize mechanolumine
