Abstract: | We observed clear fractoluminescence in crystalline quartzite, quartz crystal and fused silica at uniaxial compressional loading tests by commercial digital cameras. These fractoluminescence are composed of blue and red colors. In particular, a blue color does not appear in fractures of fused silica but appear in crystalline quartzite and quartz crystal, which implies that the piezoelectric charge and discharge play a key role in the blue-color fractoluminescence via excitation of N2 molecules. |
