Physics:Mechanoluminescence

Mechanoluminescence is light emission resulting from any mechanical action on a solid. It can be produced through ultrasound, or through other means.

• Electrochemiluminescence is the emission induced by an electrochemical stimulus.
• Fractoluminescence is caused by stress that results in the formation of fractures, that in turn yield light.
• Piezoluminescence is caused by pressure that results in elastic deformation and large polarization from the piezoelectric effect.

• Sonoluminescence is the emission of short bursts of light from imploding bubbles in a liquid when excited by sound.
• Triboluminescence is nominally caused by rubbing, but sometimes occurs because of resulting fractoluminescence. It is often used as a synonym.
