闪烁体与光子人工微结构

Scintillators boosted by nanophotonics

在核医学成像、高能物理实验和核武器研究的推动下,人们对辐射探测系统中的闪烁体提出了越来越高的要求。把传统闪烁体与先进微纳光子学技术相结合,利用光子人工微结构对电磁波的调控作用,为实现闪烁体更高的性能提供新方法和新途径。文章介绍了近期国内外利用光子人工微结构提高闪烁体性能的研究进展,也对一些可能采用的方法进行了展望与分析,该研究目前处于起步阶段,然而初步研究结果已经显示出了诱人的发展前景。

With the rapid development of nuclear medical imaging, high-energy physics experiments and nuclear weapons, the requirements for scintillators become more and more se-vere. However, there are less and less potential new materials, while currently available materials are close to their theoretical limits. In this review, we present recent developments in the combina-tion of scintillators with engineered photonic structures. Although we are just beginning, we can expect tremendous progress in the near future.
