description

The peculiarities of colour centre production and recombination in KBr, KI crystals doped with Tl, In are examined. The photostimulated dopant ion luminescence (PSL response) follows that of the F-centre production in the subnanosecond time range. It is concluded that the radiation defects in a doped crystal are spatially distributed in the near vicinity of the dopants. To a limited extent the photo- and thermostimulated defect recombination also takes place near the dopant.
