Bending Strength Dependence of Fractoluminescence Intensity in Silica Glass, Single Crystal and Polycrystalline MgO

Fractoluminescence (FL) intensity and bending strength were simultaneously measured in silica glass, single crystal and polycrystalline MgO to study dependence of the FL on mechanical properties. In the silica glass, the FL intensity was positively correlated with the bending strength. Also, the pos...
