BermanThere was an article in the last few months in the New York Times Tuseday Science section of stress-induced luminensence in a variety of materials. Some sugars, i.e. mint-flavored lifesavers, some polymers, i.e. scotch tape, are good candidates for this phemonenon. Basically, the luminesece is the result of electron transitions in outer non-spherically symmetric bands caused by stress that appear in the near-visable wavelength ranges. Related phenomena are piezoelectric materials whose conductivity (polarization) Changes when bulk forces are applied.
