Multiphoton generation of interacting charge carriers in α-quartz

Not Accessible

Your library or personal account may give you access


Above bandgap (> 8.4 eV) electronic excitation of α-quartz yields transient electron-hole pairs, which are known to recombine radiatively after self-trapping. Sometimes the decay of the self-trapped exciton (STE) results in the formation of permanent defects, such as the singly ionized oxygen vacancy. Such defects change the optical properties of α-quartz and fused silica and may occur in fibers. Their dynamics are important to understand the fundamental mechanisms of radiation damage in large-bandgap insulators.
