Abstract
Impact of short-time radiation pulse on optical materials initiates luminescence flash, formation and transformation of color centers (defects) in them. The present paper is devoted to the study of the mechanisms of the occurrence of the luminescence buildup stage in LiF-WO3 and YLiF4:Nd3+ crystals in which this effect is found to be steady at 300 K after exposure to the high-energy electron flux pulse of nanosecond duration, also proposed a model to describe the kinetics of cathodoluminescence growth under pulsed excitation.
