Outline of Final Research Achievements

Some garnet, sesquioxide, and perovskite transparent scintillators were developed. Based on results of my master thesis, Ce-doped Gd3(Al,Ga)5O12 showed the highest scintillation performance, such as high light yield of 70000 ph/MeV, fast decay time of 100 ns, and medium energy resolution of 10% at 662 keV. i found new knowledge that the energy migration efficiency can be improved by introducing impurity phase.
