Abstract The development of scintillators with fast uorescence rise and decay times is required for the ac­
curate synchronization adjustment of XFEL femtosecond pulses with short pulses from other light sources forpump and probe experiments. An intentionally iron­doped, hydrothermal­method­grown, ZnO scintillator wasdemonstrated to exhibit a response time faster by over one order of magnitude for EUV_FEL than conventionalnon­doped ZnO crystals.
