摘要:

随着我国核辐射技术的进步, 辐射探测在近些年也得到了高速发展, 并被广泛应用于辐射安全监测、放射性医学诊疗、X射线安监系统、工业无损探伤以及微观粒子轨迹探测等诸多领域。辐射光致发光(Radio- photoluminescence, RPL)是一种在电离辐射作用下, 材料内部产生新的发光中心, 并被紫外光激发进而发光的现象, 可作为一种新型辐射探测手段。RPL材料通常具有存储辐射信息、信息几乎不衰减、剂量线性响应好、均匀稳定的高辐射灵敏度、能量依赖性小和可重复读数等特点, 弥补了光释光(Optically stimulated luminescence, OSL)和热释光(Thermally stimulated luminescence, TSL)材料在存储稳定性和重复使用性等方面的不足。自RPL现象被报道以来, RPL材料层出不穷, 如传统的Ag掺杂磷酸盐玻璃、Al2O3:C,Mg和LiF, 再到新型的Cu离子掺杂体系、Sm离子掺杂体系以及无掺杂体系材料等。同时, RPL应用也被不断发掘, 目前它已成为辐射探测领域不可或缺的材料之一。基于此, 本文概述了RPL材料的最新进展, 重点梳理了传统和新型RPL材料的发光原理、性能特点及其应用, 特别对比了不同RPL材料在辐射探测性能方面的差异。最后, 本文对RPL材料的优势及其不足之处进行了归纳分析, 并对其发展趋势进行了展望。

Abstract:

With the progress of nuclear radiation technology in China, radiation detection has been developed rapidly in recent years for the wide usage in radiation safety monitoring, radioactive medicine diagnosis/treatment, X-ray security inspection, industrial non-destructive detection, microscopic particle track detection, and many other fields. Radio-photoluminescence (RPL), as a new radiation detection method, is a phenomenon in which a new luminescence center is generated inside a material under a ionizing radiation which can be excited by ultraviolet light to emit a special light. RPL materials usually have characteristics of storing radiation information, almost no attenuation of information, good linear dose response, high radiation sensitivity, low energy dependence, and repeatable reading, which can overcome the shortcomings in stability and reusability of optically stimulated luminescence (OSL) materials and thermally stimulated luminescence (TSL) materials. Since the RPL phenomenon was reported, RPL materials have emerged constantly, from the traditional materials as Ag-doped phosphate glass, Al2O3:C, Mg and LiF, to the novel materials such as Cu-doped RPL system, Sm-doped RPL system and undoped RPL system materials. Meanwhile, applications of RPL materials have also been explored, enabling them to become one of the indispensable materials in the field of radiation detection. Based on above aspects, this paper summarizes the latest development of RPL materials, focuses on the luminescence principle, performance characteristics and applications of traditional and novel RPL materials, and especially compares the performance of different RPL materials in radiation detection. Finally, advantages and disadvantages, accompanied by prospected development trend of RPL materials are summarized and analyzed

Key words: radio-photoluminescence, radiation detection, dose detection, Ag-doped phosphate glass, X-ray imaging
