Optical Destruction and Restoration of {F, In2+} Pairs in KBrIn Crystals

Using photostimulated luminescence of {F, In+} defect pairs in KBr‐In crystals, their F‐light optical destruction under excitation has been investigated. It is shown that the effective absorption cross‐section of F centers manifests itself in the kinetics of photostimulated luminescence of {F, In2} pairs under constant F‐stimulation. It is shown also that the resulting products ‐ {va+, In+} pairs ‐ may be again converted to {F, In2+} under C‐absorption band illumination.
