摘要/Abstract

摘要： 核辐射探测是指用各种核辐射探测器来得到核辐射信息的过程,在军用、民用和科研等领域具有广泛的应用。作为核辐射探测核心的核辐射探测器,主要分为气体探测器、闪烁体探测器和半导体探测器。相比于气体探测器,闪烁体探测器和半导体探测器都需要晶体作为核心材料,晶体质量的品质在很大程度上决定了探测器性能的上限。为了获得性能更好的探测器,人们对探测器用单晶材料的生长方法进行了大量的研究。本文综述了近几年核辐射探测单晶生长方法研究的最新进展,总结了目前主流的晶体生长方法,包括溶液法、熔体法、气相法等,并对不同晶体的主要生长方法进行了归纳。

Abstract: Nuclear radiation detection refers to the process of using various nuclear radiation detectors to obtain nuclear radiation information, which has a wide range of applications in the fields of military, civil and scientific research. As the core of nuclear radiation detection, nuclear radiation detectors are mainly divided into gas detectors, scintillator detectors and semiconductor detectors. Compared with gas detectors, both scintillator detectors and semiconductor detectors need crystals as core materials, and the quality of crystals largely determines the upper limit of detector performance. In order to obtain detectors with better performance, a large number of growth explorations have been carried out on single crystals. This paper reviews the latest research progress of single crystals for nuclear radiation detection in recent years, summarizes the current mainstream growth methods, including solution method, melt method and gas phase method, and the main growth methods of different single crystals for nuclear radiation detection are generalized.

Key words: nuclear radiation detection, single crystal, crystal growth, solution method, melt method, gas phase method
