At the 68th Japan Society of Applied Physics (JSAP) Spring Meeting on March 16-19, 2021, Mr. Prom Kantuptim (1st year doctoral student) of Applied Quantum Physics (formerly Sensing Device) Laboratory received the Poster Award from the conference committee. The award was given to 14 outstanding posters from 529 all poster presentations at the conference.

First of all, I would like to humbly thanks the co-authors including professor Yanagida, associate professor Kawauchi, and all the applied quantum physics (sensing device) laboratory staff. My sincere thanks also extend to laboratory members. This work could not be successfully achieved without their guidance. I always give high priority to create the optimum ways to deliver my work to the science community. I believe a good presentation will encourage a good discussion from the expert in the field, and that is one of the best ways to improve the research. Finally, I would like to share my award with fellow students at NAIST who have dedicated their effort to research in this difficult time of the COVID-19 pandemic. I wish you are greatly successful in the research, and also the private life.

The scintillator is one of the phosphor materials that can convert the high energy ionizing radiations such as photons (X- or γ-ray), neutron, or charged particles into lower-energy photons such as ultraviolet, visible, and near-infrared light. The combination of scintillator and photodetector has been widely used for radiation measuring instruments in many scientific fields. The study of inorganics scintillator is always looking for new materials that have high light yields, fast scintillation decay time, good energy resolution, and low afterglow. All of these desirable properties can be found in the lanthanide-doped materials, especially with Ce. This research has the aim to study and investigate the La2Si2O7 (LaPS) for the new host materials for Ce on both optical and scintillation properties.
