Abstract:

The kinetics of pulsed cathodoluminescence, which appears upon irradiation of condensed media with high-power electron beams of nanosecond duration, is analyzed. Four types of emission are considered: recombination emission, exciton emission, intracenter emission, and emission of electron and hole centers. It is found that the maximum difference in the kinetics of the intensities of emission of these types occurs in the time interval t less than or equal to t(1) approximate to A(-1), and, in the far afterglow, an exponential decay occurs with the characteristic time (2A)(-1) for the first and second types of luminescence and A(-1) for the fourth type. For the intracenter luminescence, the decay time is equal to (2A)(-1) and A(i)(-1) for short-lived and long-lived radiative levels, respectively (A and A(i) are the probabilities of linear recombination of electron-hole pairs and decay of a radiative level, respectively). In the case of long-lived radiative levels, a strong peak is observed in the spectrum of intracenter luminescence in the far afterglow. (C) 2003 MAX ``Nauka/Interperiodica{''}.
