Abstract : A cathodoluminescence system was modified to enable pulsed operation of the electron gun and detection of the time dependent luminescence. Time resolved spectra and intensity decay curves as well as continuous excitation spectra of some previously reported violet, green, and red peaks in the cathodoluminescence of ZnO were made. The resulting observed shifts in wavelength of the violet peaks with time suggests a bound-to-bound transition. The absence of any change in decay with wavelength in the red peak suggests that it is not due to bound-to-bound transitions.
