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, Eu~(2+)，的发光强度远高于Eu~(3+)的发光强度，Eu~(3+)对Eu~(2+)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．

关键词: BaFBr:Eu, Eu2+和Eu3+, 光激励发光, 穆斯堡尔谱, 发射光谱

Abstract:

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 Eu~(2+) is much higher than that of Eu~(3+), Eu~(2+) lundnescence Anght be enhanced by Eu~(3+). Meanwhile, Mossbauer 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.

Key words: BaFBr:Eu, Eu2+ and Eu3+, Photostimulated luminescence, Mossbauer spectrum, Emission spectrum
