机械发光，也被称为摩擦发光或断裂发光，是由于机械作用于固体而产生的光发射，例如，弗朗西斯·培根早在1605年就指出，糖块在刮擦时会发光。在这里，我们通过一种新的方法--声空化来激发机械发光，并发现强烈的发光和发射线是其他机制所不能产生的，例如研磨、劈裂、摩擦、划痕、咬合或热冲击。
Mechanoluminescence, also known as triboluminescence or fractoluminescence, is light emission induced as a result of mechanical action on a solid,,— for example, Francis Bacon noted as long ago as 1605 that lumps of sugar emitted light when scraped. Here we elicit mechanoluminescence by a new means, acoustic cavitation, and find intense luminescence and emission lines that are not generated by other mechanisms such as grinding, cleaving, rubbing, scratching, biting or thermal shock.
