The molybdenum doping level varied from 1 to 30%. The tendency of Mo to create energy states within the bandgap of ZnO and theirinfluence on the energy levels of native defects as well as excitons were proven by the synergy ofexperiment and theory. The improvement of the timing characteristics of the exciton- and zincvacancy-related emission bands upon Mo doping (1-10%) was observed. This paves the way for the defect engineering strategy in the search of effective and ultrafast scintillator with the improved lightyield as well as compared to other materials. The new concept is based on the combination of theexciton and the defect emission. It is expected to have the potential of application in the detection ofgamma rays implemented in time-of-flight positron emission tomography (TOFPET).
