A number of different radiation detection applications require scintillators with high light output, good attenuation power, low afterglow, and very fast decay times. Fast decay times are of primary importance in positron emission tomography (PET) and nuclear physics experiments. Zinc oxide doped with gallium is known for its fast scintillation properties (sub-nanosecond decay time) under a variety of excitation conditions (alpha, gamma, UV). The expanded development of synchrotron radiation for the investigation of advanced materials has only underscored the need for continued development. This work investigates the effect that synthesis method (urea precipitation, solution phase, combustion synthesis) has on gallium incorporation, particle size and distribution and resulting emission using a wide variety of analytical techniques.
