Abstract The paper deals with the development of X-ray imaging composite detectors based on GAGG:Ce powders bound by the organic polysiloxane matrix. The luminescence intensity was improved through optimization of solid state reaction conditions and Ce concentration in GAGG:Ce. The deviation of light output over the detector square does not exceed ±6%. The spatial resolution of 130 μm was achieved with the optimized GAGG:Ce composite detectors.

GAGG：用于X射线成像的Ce复合闪烁体

摘要 本文研究了基于有机聚硅氧烷基体结合的 GAGG:Ce 粉末的 X 射线成像复合探测器的开发。通过优化固态反应条件和 GAGG:Ce 中的 Ce 浓度，提高了发光强度。探测器方格上的光输出偏差不超过±6%。使用优化的 GAGG:Ce 复合探测器实现了 130 μm 的空间分辨率。
