摘　　要：首次应用穆斯堡尔谱对光激励发光材料BaFBr：Eu进行了研究．穆斯堡尔谱的研究结果印证了光谱学研究得出的结论，即在BaFBr:Eu中：Eu2＋，的发光强度远高于Eu3＋的发光强度，Eu3＋对Eu2＋的发光有增强作用．穆斯堡尔谱的研究还为声子对发光中心的影响提供了有用的信息．这些结果对于发光机制的认识是很有帮助的．Mossbauer spectroscopy is uesd to study the photostimulated luminescence material BaFBr:Eu for the first time. The results from Mossbauer study support the conclusion obtained from luminescence studies, that is in BaFBr:Eu, the ltalnescence effect of Eu2+ is much higher than that of Eu3+, Eu2+ lundnescence Anght be enhanced by Eu3+. Meanwhile, M6ssbauer study may also provide useful information on the interaction of phonon on luminescence centers. All thoes results are helPful to the understanding of luminescence process.
