Abstract
A mechanoluminescence material comprising a mother body material and a luminescence center added to the mother body material. The mother body material is constituted of at least one kind of oxide selected from alumino silicate, aluminate, silicate, tantalate, niobate, gallium oxide, and ZrO2, and the luminescence center is at least one kind selected from a rare earth metal and a transition metal which emits light when electrons excited by mechanical energy are restored to a normal state.
