摘要：

Electron injection has been carried out in single crystals of pure KCl and KBr under constant field for different temperatures. The injection current and optical density as a function of time are measured for both growth and decay process to estimate the mobility of colour center. The activation energy for bleaching of trapped centers and corresponding dissociation energy have been calculated.
