Triboluminescence activity and charge produced during fracture have been measured in many organic crystals of the orthorhombic system. The crystals belonging to disphenoidal and pyramidal classes which are piezoelectric exhibit triboluminescence, however, the crystals belonging to the dipyramidal class which are non-piezoelectric do not exhibit triboluminescence. This fact suggests the piezoelectric origin of triboluminescence and shows that triboluminescence is a structure-sensitive property of the crystals.
