Transient behaviour of the mechanoluminescence induced by impulsive deformation of fluorescent and phosphorescent crystals

Experimental and Theoretical Study of the Mechanoluminescence of ZnS:Mn Nanoparticles

“…It has been reported that ML response of ZnS:Mn are similar to those of piezoelectric voltage responses. [23][24][25] Figure 5 shows a plot of impact velocity as a function of maximum ML intensity, I M (Fig. 5a), and total ML intensity, I T (Fig.…”

Mechanoluminescence and thermoluminescence of Mn doped ZnS nanocrystals

“…However, the radiation intensity in most of the materials is too weak and difficult to detect. For better understanding of the mechanoluminescent materials significant theoretical studies have also been made on the EML, PML, and FML [21][22][23][24]. In the recent past the intense elasto-and fracto-mechanoluminescent materials have been found to have the potential for the stress sensor, fracture sensor, damage sensor, impact sensor, and for the visualizations of stress field near the crack-tip, stress distribution in the solids, and quasi-dynamic crack propagation in solids [25][26][27][28][29][30].…”

Mechanoluminescence by impulsive deformation of γ-irradiated Er-doped CaF2 crystals

“…ML has found various important applications such as impact sensors in spacecrafts (the emission intensity can be used to determine the kinetic energy of impact), fracture sensor, damage sensor, sensor for stress and its distribution in the solids, crack propagation in solids and understanding of the basic mechanism of crack growth [9][10][11]. Chandra et al [4,[12][13][14][15] have presented the various theoretical studies on various kinds of ML.…”
