Transparent ceramics have great potential as a host structure for scintillation material because of their excellent physical properties such as high density, chemical radiation stability as well as superb optical properties. Ceramic processing route offers an attractive alternative to obtain scintillator materials for medical imaging, medical radiographs, and homeland security applications at relative low temperature and cost. It gives an options to fabricate scintillator compositions that are not melt congruently and therefore not achievable via melt crystal growth. And it offers flexibility in activator concentration adjustment.
Cerium-doped Garnets Lu3Al5O12 (LuAG), (Gd,Lu)3(Ga,Al)5O12 (GLuGAG) and Gd3 (Ga,Al)5O12 (GGAG)) feature high density, high effective atomic number and excellent scintillation properties and are good candidates for the above-mentioned applications. In this study, transparent garnet ceramic scintillators were synthesized and the optical and scintillation properties were measured. The relationships between processing conditions such as ceramic stoichiometry and thermal annealing conditions and optical properties were compared and discussed.
