摩擦发光
摩擦发光(英语:Triboluminescence)是将材料拉开、撕开、刮划、压碎或互相摩擦而发光的现象(参见摩擦学)。这现象尚未完全了解,但似乎是由静电荷分离又结合引起。术语来自希腊语τρίβειν(“摩擦”)和拉丁语lumen(光)。破开糖晶体和撕胶纸时可观察到摩擦发光。
例子
普通材料
某些居家材料和物质可展示此特性:
- 普通压敏胶纸(“透明胶纸”)与胶纸卷分离的地方会发光。[1]苏联科学家在1953年观察到在真空撕胶纸会发X光。[2]2008年,X光生成机制获进一步研究。[3][4][5]类似的X光也可在金属中观察到。[6]
- 在黑暗中打开用胶水黏着的信封可看到蓝色闪光。[来源请求]
- 破开糖晶体会产生微小电场分开正电荷和负电荷,电荷试图结合时产生火花。Wint-O-Green Life Savers特别适合产生这种火花,因为冬青油(水杨酸甲酯)是荧光物,可将紫外线转化为蓝光。[7][8]
