Classification of Mechanoluminescence

AbstractOn 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) baro 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 tribo ML, (xx) chemically‐induced tribo ML, (xix) electrically induced tribo ML, (xx) chemically‐induced tribo ML, and (xxi) thermally‐induced tribo 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.
