![]() The exact reasons why particular materials show triboluminescence can be different for different materials, but it is probable that crystal structure and impurities are primary determinants of whether or not a material is triboluminescent. These irregularities, or localized asymmetries, also allow for an electrical charge to collect. Impurities, disorder, and defects are also common in triboluminescent materials. Terms/Concepts: Triboluminescence Glow-in-the-dark Methyl Salicylate Sugar. Therefore, an additional characteristic must determine triboluminescence. Wintergreen candy- Lifesavers, Tic Tac, Altoids, Starlights, etc Mirror. However, about a third of known triboluminescent materials are not piezoelectric and some piezoelectric materials are not triboluminescent. Asymmetric, piezoelectric materials are more likely to be triboluminescent than symmetric substances. An asymmetric molecule changes its ability to hold electrons when squeezed or stretched, thus altering its electric charge distribution. Sucrose molecules and crystals are asymmetric. Piezoelectric materials generally have an asymmetric (irregular) shape. If you do this to a Wint-O-Green Life Saver, you can see a much greater amount of light (blue sparks) due to the wintergreen flavoring or methyl salicylate. Piezoelectric materials generate an electrical voltage from the separation of positive and negative charges when they are squeezed or stretched. Why do Wint-O-Green Life Savers spark in the dark This is due to triboluminescence, which is the emission of light resulting from something being smashed or torn. Triboluminescence is related to piezoelectricity. 16 reviews for LifeSavers Mints Wint O Green. ![]()
