Ionic Transport in Alkali Halides with Doping-Induced Defects and Colour Centre Migration by Thermal Bleaching
Measurements of ionic conductivity in pure alkali halides and in alkali halides with doping-induced defects were made to determine the activation energies and mobility of F-centres. The activation energies in NaCl:Cd+2 were found large in comparison with NaCl with other divalent impurities. The mobilities of F-centre migration on bleaching of injected electrons were measured and the activation energies of bleaching WF have been found. The results for space-charge-limited conduction of F-centres are explained with the determined values of activation energies W and WF.
