| Outline of Final Research Achievements |
The advantage of transparent ceramic scintillators are high energy transfer efficiency due to the suppression of nano-scale defect and high transfer efficiency of optical photons via controlling the micro-scale grain. In order to develop efficient scintillators, doping of some ions which do not posses electron levels for luminescence sometimes works well. In this study, we developed new scintillators by controlling these properties. As a result, we achieved the light yield of 70000 ph/MeV, scintillation decay time of 80 ns, and energy resolution of 6% at 662 keV one year before the end of this project.
