Meaning and Definition
The emission of light caused by mechanical action on a material, such as crushing, rubbing, or scratching.
A physical phenomenon where light is generated through the breaking of chemical bonds in a material when it is pulled apart, ripped, scratched, crushed, or rubbed. It is a subset of mechanoluminescence.

- Confusing it with chemiluminescence (light from chemical reaction) or bioluminescence (light from living organisms).
FAQ
Frequently Asked Questions
Yes, that is a classic demonstration. The crushing of the sugar crystals creates the effect, and the wintergreen oil (methyl salicylate) fluoresces, making the blue light appear brighter green to our eyes.
They are related but distinct. Piezoelectricity is the generation of an electric charge in certain materials under mechanical stress. This electric discharge can sometimes cause triboluminescence in the surrounding air, but triboluminescence can also occur through other mechanisms like crystal fracture.
No, it is a property of specific materials with asymmetrical crystal structures, such as quartz, sugar, and certain minerals. Symmetrical crystals like sodium chloride (table salt) typically do not show the effect.
Currently, it is not efficient enough for general lighting. However, it has niche applications in research for stress sensors, damage detection in materials, and even in novel concepts for self-powered lighting in extreme environments.
The emission of light caused by mechanical action on a material, such as crushing, rubbing, or scratching.
Triboluminescence is usually technical/scientific in register.
Triboluminescence: in British English it is pronounced /ˌtraɪ.bəʊˌluː.mɪˈnes.əns/, and in American English it is pronounced /ˌtraɪ.boʊˌluː.məˈnes.əns/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think of 'tribo-' as in friction or rubbing (like 'tribology'), and '-luminescence' as light emission. So, 'light from rubbing'.
Conceptual Metaphor
LIGHT IS A SUBSTANCE RELEASED BY FORCE (The crushing 'releases' trapped light).
