摘要：

Electric current output or scintillation light from solid-state inorganic materials under ionizing radiation is very useful for nuclear and radiation detection. Direct electric current measurements in semiconductors or ionic crystals provide high resolution spectroscopy and imaging capability even though there are scalability and cost issues. In contrast, inorganic scintillation materials utilizing photons generated by incident radiation have been developed for many decades and provide better scalability and lower cost. Ceramic materials offer compelling advantages including large size, mechanical strength, and homogeneity. In this work, we review current status of advanced radiation detection materials and introduce our efforts in the development of ceramic scintillator materials, mainly for gamma ray detection.
