Abstract Zinc oxide (ZnO) has attracted attention as an energy conversion material for optoelectronics and ionization radiation detector applications. ZnO thin films were fabricated on quartz substrates by using sol-gel and hydrothermal methods. The structural and the optical properties of ZnO thin films before and after gamma irradiation (0, 54.72, 109.44 and 164.16 kGy) have been systematically investigated. After irradiated with high dose gamma-ray: grain size has decreased; optical band-gap exhibited red-shift; radiation generated defect improved radiative recombination and affected Zn–O bond. The results indicated ZnO materials show high radiation hardness under high dose gamma-ray (60Co) radiation environment.

溶液生长垂直 ZnO 纳米线的高剂量伽马射线效应

摘要 氧化锌 (ZnO) 作为用于光电子学和电离辐射探测器应用的能量转换材料已引起人们的关注。采用溶胶-凝胶法和水热法在石英衬底上制备了 ZnO 薄膜。已经系统地研究了伽马辐射（0、54.72、109.44 和 164.16 kGy）前后 ZnO 薄膜的结构和光学特性。高剂量伽马射线照射后：晶粒尺寸减小；光学带隙呈现红移；辐射产生的缺陷改善了辐射复合并影响了 Zn-O 键。结果表明，ZnO 材料在高剂量伽马射线 (60Co) 辐射环境下表现出高辐射硬度。
