Cathodoluminescence kinetics of Li6GdB3O9 crystals

The pulse cathodoluminescence kinetics of Li6GdB3O9 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.
