There 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.
