Abstract

In order to adapt to the rapid development of high-speed imaging technology in recent years, it is very important to develop scintillators with an ultrafast time response. Because of its radiation-induced ultrafast decay time, ZnO has become an important material for radiation detection and dosimetry. According to different detection sources and application scenarios, ZnO is used in various radiation detectors in different structures, including nanoarrays and nanocomposites. In this paper, the synthesis methods and research status of various nanostructured ZnO-based materials and their applications in the detection of high-energy rays (X-rays, γ-rays) and high-energy particles (α, β and neutron) are reviewed. The performance discussion mainly includes spatial resolution, decay time and detection efficiency.

摘要

为了适应近年来高速成像技术的快速发展，开发具有超快时间响应的闪烁体非常重要。由于其辐射诱导的超快衰减时间，氧化锌已成为辐射探测和剂量测定的重要材料。根据不同的探测源和应用场景，氧化锌以不同结构用于各种辐射探测器，包括纳米阵列和纳米复合材料。本文综述了各种纳米结构的氧化锌基材料的合成方法、研究现状及其在高能射线（X射线、γ射线）和高能粒子（α、β和中子）探测中的应用。性能讨论主要包括空间分辨率、衰减时间和探测效率。
