Application of Luminescent Materials for Radiation Detection (#442)

Various luminescent materials have been used for the detection of ionizing radiation. Radiation detection using luminescence includes scintillation, thermoluminescence, optically stimulated luminescence, and radio–photoluminescence. These luminescence processes have been used to detect ionizing radiation in various fields of science and industry, such as basic physics, nuclear medicine, environmental monitoring, and radiography. The demand for higher-quality materials has increased owing to emerging applications in various fields and the nuclear plant accident in Japan. Novel high-quality materials can contribute greatly to various fields. In contrast to optical excitation in which well-defined excited states are produced, various kinds of excited states are involved in luminescence processes under ionizing radiation. At present, however, the mechanism underlying the various luminescence processes under ionizing radiation is unknown. In order to develop higher-quality materials, the development of novel materials and an investigation into the basic processes associated with excited states are both quite important.
This symposium showcases the recent achievements in this field from the viewpoint of materials chemistry. The symposium focuses on the following areas: 1) the development of novel luminescent materials for radiation detection, 2) research on the novel functionality of conventional optical materials for radiation detection, and 3) investigation into the basic processes of luminescence under or after irradiation.
