At the 7th meeting of the Japan Society of Applied Physics Frontier Research Group of Extreme Excitation and Quantum Energy Conversion in Ishikawa, Mr. Prom Kantuptim (a D2 student) of the Applied Quantum Physics Laboratory received Young Scientist Presentation Award. The award was given to 7 outstanding presentations from 40 all poster presentations at the conference.

I would like to present my sincere gratitude to professor Yanagida, professor Watanabe of Kyushu university, and the applied quantum physics laboratory staff for academic support. This study is a collaborative project between NAIST and Kyushu University, and it was a great opportunity to work with 2 professors at the same time. This award will encourage me to keep doing and improving the quality of the research. Finally, I would like to share this award with my friends at the applied quantum physics laboratory and my friends at NAIST who do their best effort during this difficult time of the COVID-19 pandemic.
A series of 1.0% Tb-doped rare-earth pyrosilicate single crystals including Lu2Si2O7, Y2Si2O7, Gd2Si2O7, and La2Si2O7 has been prepared by the floating-zone method. After the phase confirmation by powder X-ray diffraction, the photoluminescence and scintillation properties were evaluated. Under γ-ray irradiation from 137Cs, Tb-doped Gd2Si2O7 showed scintillation light yield of 95,600 ph/MeV , which is considered to be one of the highest values among the oxide scintillator.
