碱土金属复卤化物的光激励发光已有大量的研究工作.由于色心在光激励发光及影像的存储过程中起着非常重要的作用,是人们一直关心的课题.对这类晶体的F心、V心及氧中心都进行了较多的研究,为光激励发光的认识提供了重要的实验依据.我们报道了BaFCI:Eu~(2+[8]),BaFBr:Eu~(2+[9])和SrFCI:Eu~(2+[10])晶体的新型电子色心,并讨论了这些色心的光激励发光及其意义.本文将简单介绍BaFl:Eu~(2+)晶体中的新型色心及其发光. There are a lot of research work on photoluminescence of alkaline earth metal complex halides. Since the color center plays a very important role in photoluminescence and image storage, it is a topic that people are always concerned about. , V centers and oxygen centers have been studied more and more, which provides important experimental evidences for understanding the photoluminescence.We reported BaFCI: Eu ~ (2+ [8]), BaFBr: Eu ~ (2+ [ 9]) and SrFCI: Eu ~ (2+ [10]) crystals were discussed in detail, and their photoluminescence and their significance were discussed. In this paper, The new color center and its light.
