CLASSIFICATION OF MECHANOLUMINESCENCE

On the basis of the processes involved in inducing luminescence, mechanoluminescence (ML) may be classified into different types, such as: (i) piezo-electrification-induced fracto ML, (ii) defective-phase piezo-electrification-induced fracto ML, (iii) charged dislocation electrification-induced fracto ML, (iv) bare diffusion electrification-induced fracto ML, (v) chemically-induced fracto ML, (vi) thermally stimulated fracto ML, (vii) incandescent fracto ML, (viii) stress perturbation-induced fracto ML, (ix) thermal excitation-induced fracto ML, (x) mechanically excited ML, (xi) deep trap-induced fracto ML, (xii) dislocation mechanical interaction-induced plastico ML, (xiii) dislocation electrostatic interaction-induced plastico ML, (xiv) charged dislocation electrification-induced plastico ML, (xv) thermal excitation-induced plastico ML, (xvi) dislocation mechanical interaction-induced elastico ML, (xvii) dislocation electrostatic interaction-induced elastico ML, (xviii) thermal excitation-induced elastico ML, (xix) electrically induced tribe ML, (xx) chemically-induced tribe ML, (xix) electrically induced tribe ML, (xx) chemically-induced tribe ML, and (xxi) thermally-induced tribe ML. It is expected that the processes involving dislocation electrostatic interaction-induced elastico ML and thermal excitation-induced elastico ML may provide suitable ML materials in future.
