Outline of Final Research Achievements |
In this research project, the development of low-cost high-sensitivity X-ray devices is carried out based on the high durability of lead halide perovskites against radiation. It has been shown that single crystals of lead halide perovskites can be used for radiation detection with high sensitivity. In this study, instead of the recrystallization method, the heat-pressing method from the powder were carried out to fabricate pseudo-single crystal, which is considered to be more efficient for the fabrication of the devices. Although the desired performance as an X-ray device was not obtained, the establishment a basis for investigating the high durability of the material under electron irradiation have been proceeded.

Academic Significance and Societal Importance of the Research Achievements |
放射線診断機器の小型軽量化は、骨折、じん肺、尿路結石、心臓血管系疾患の早期診断と発見にも大きく貢献する。また、材料の欠陥診断やセキュリティ装置などの応用範囲も広い。その普及には、安価で製造可能であり、高分解能、高耐久性の放射線検出材料が必要となる。X線を検出に必要なハロゲン化鉛系ペロブスカイト厚さは数mmである。本研究では、このような素子の作製条件に関するデータを蓄積した。
