Abstract : The present paper gives study of Fracto- mechanoluminescence induced by slow deformation of fluorescent and phosphorescent crystals. In slow deformation of a crystal, the number of ML pulses emitted indicates the number of cracks moved in the crystal. Thus, there is one-to-one correspondence between the number of cracks formed and the number of ML pulses emitted during the deformation of crystal. The study of fracto-ML gives important information that the number of cracks increases linearly with the deformation of crystals and the area of newly created surfaces at slow strain increases linearly with the strain of crystals.
