A report on Triboluminescence

Triboluminescence of Nicotine-L salicylate
An Uncompahgre Ute Buffalo rawhide ceremonial rattle filled with quartz crystals. Flashes of light are visible when the quartz crystals are subjected to mechanical stress in darkness.

Phenomenon in which light is generated when a material is mechanically pulled apart, ripped, scratched, crushed, or rubbed .
