Abstract:
The pulse cathodoluminescence kinetics of Li$_{6}$GdB$_{3}$O$_{9}$ crystals in the form of both the single crystal and crystal-fiber have been studied using time-resolved absorption and luminescence spectroscopies upon excitation with a nanosecond electron beam at 293 K. Mechanism for pulse cathodoluminescence excitation has been developed on the basis of the numerical modeling of recombination processes.
