Abstract
The peculiarities of colour centre production and recombination in KBr , KI crystals doped with T1, In are examined. The photostimulated dopa nt ion luminescence (PSL response) follows that of the F-centre produc tion in the subnanosecond time range. It is concluded that the radiati on defects in a doped crystal are spatially distributed in the near vi cinity of the dopants. To a limited extent the photo- and thermostimul ated defect recombination also takes place near the dopant.
