Mechanoluminescence(ML) the phenomenon of cold light emission induced during mechanical deformation of solids links the mechanical, spectroscopic, electrical, structural and other properties of solids . A large number of organic, inorganic crystals and amorphous solids exhibit the phenomenon of (ML). The studies on the ML produced during pulse-induced excitation in crystals has been interesting as it provides important information concerning the nature of the luminescence centre's and helps in understanding their basic mechanism of ML excitation in solids
