Abstract Polymer based scintillation detectors have an important role in the radiation detection, medicine and nuclear energy. In this study, attempts have been made to prepare a scintillating particle composite by suspending of highly luminescent gallium doped zinc oxide (GZO) powders in an epoxy matrix. The GZO powder was synthesized by a low cost sol-gel method. X-ray diffraction analysis, X-ray photoelectron spectroscopy and Raman spectroscopy confirmed that GZO powders were successfully prepared. The average crystallite size of GZO nanoparticles was also calculated and found to be in the range of 31–32 nm. The scintillation response of GZO epoxy composite was measured using an Am–Be source. The fabricated nanocomposite showed good neutron radiation sensitivity and remarkable blue emission peak (~485 nm) at room temperature. Our investigations showed that GZO composite has a good potential to be used as a scintillator material and can be prepared easily by simple laboratory equipment.

通过在环氧聚合物中捕获 ZnO: Ga 纳米晶体来实现新的闪烁特性

摘要 基于聚合物的闪烁探测器在辐射探测、医学和核能领域具有重要作用。在这项研究中，尝试通过将高发光度的掺镓氧化锌 (GZO) 粉末悬浮在环氧树脂基质中来制备闪烁粒子复合材料。GZO 粉末是通过低成本的溶胶-凝胶法合成的。X射线衍射分析、X射线光电子能谱和拉曼光谱证实GZO粉末制备成功。还计算了 GZO 纳米颗粒的平均微晶尺寸，发现其范围为 31-32 nm。使用 Am-Be 源测量 GZO 环氧复合材料的闪烁响应。制备的纳米复合材料在室温下表现出良好的中子辐射敏感性和显着的蓝色发射峰（~485 nm）。
