Abstract
Abstract—The spectrum is obtained and the time dependences of fractoluminescence signals upon fracture of the surface of quartz are studied. The analysis of the obtained data has shown that at fracture, clusters of four cracks having a size of a few nm appear. Crack formation is associated with the destruction of barriers precluding the motion of dislocations along the sliding planes. The distribution of cracks by sizes (surface areas of crack walls) obeys the Gutenberg–Richter law.
