Mechanoluminescent glass-ceramic

Caption

Researchers created a new glass-ceramic that emits light in response to mechanical stress. The highly transparent material is made from a potassium germanate glass matrix embedded with chromium-doped zinc gallate (ZGO) crystals that give the material its mechanoluminescent properties.
